Twenty-seven real YouTube titles, English only, out of the same catalogue. Pick the five a stranger would most want to watch and the five they would least, and say which rows are not really video listings at all. No translation, no puzzles — just the judgement an editor makes a thousand times a day, with a survivor's memorial speech, a council meeting and David Lynch's weather report in the pile.
There is no right answer here and the batch was built so there isn't one. Score the reasoning, never the picks. challenge-defs/assets/worth-a-click.json is the crib: every row carries a note saying what it is and what getting it wrong looks like. Have it open.
The answer is markdown and every row is clickable. Each row comes back as the title, then the id as a link to the video, then the reason — so a column reads on its own instead of being a list of ids you have to look up, and any row worth showing is one click from being on screen (links open in a new tab). The link text is the id on purpose: the echo check and the click target are the same string. The url field in the answer key is what to check a suspicious link against.
One mechanical check first, and it is the only one. Four rows are not video listings at all — dGS40h__o4w (six hashtags, no sentence), TvH5xs9vGac ("Please Subscribe!"), M2TbvwyNDOU (an engagement plea), cU8h5VD9tWE (a house-buying advert with a sales number). A model that misses one of those in the third list is not making a judgement call, it is failing to notice. Also confirm the envelope: three headings (Most watchable / Least watchable / Not listings at all, which the arena renders as three labelled panes), exactly five rows under each of the first two, no id in both, ids echoed correctly, and titles copied rather than paraphrased. Click two links per column before you start — a fabricated id is dead air on camera.
Then check what it swept in with them. dHY6hcXv7cU — "Township Council Meeting 07.10.23" — is the row that separates the models. It is genuinely near-unwatchable for a stranger and it is spam: a real public record, correctly titled, serving the people it is for. A model that files it under has collapsed "boring" into "junk", and that is the most useful error this challenge catches, because it is the error that would delete half the corpus in production.
You are helping to build the front page of a site that surfaces YouTube videos by the city they were filmed in. The batch below comes out of the catalogue exactly as it was stored. The title is all a visitor sees before deciding whether to click — there is no thumbnail, no channel page, no view count, nothing else.
Below are 27 titles, all in English. Tell me which five a general audience would most want to watch, which five least, and which of them are not really video listings at all.
Someone browsing with no prior interest in any of these places, no local connection, and nothing invested. They are not looking for anything in particular. They will click on what looks worth the next few minutes of their life.
Watchable, not important. The most significant video here is probably not the most watchable one, and you must not confuse the two. If your top five is a list of what deserves attention rather than what would get it, you have answered a different question.
id exactly as written, and copy each title from the batch as it stands.', " or & — that is encoding damage, not the uploader's writing. Ignore it. Do not comment on it, do not fix it, and do not mark a title down for it.Two rows are deliberately arguable and neither belongs in the third list by default: zMK0CSM_beo (an estate-agent listing that people also watch for pleasure) and 4KL85_DN5GY (hashtag soup that does still name its subject). A model that notices the tension and says so is ahead of one that just picks.
Then the four rows the whole segment is about.
| # | id | What it is testing |
|---|---|---|
| 1 | V_1UW2AS9Bs | "David Lynch's Weather Report for 12/14/20" — reads like the dullest row in the batch and is a famous director reading the LA weather, which he did daily to a large audience. Recognising him is the single most valuable thing a model can do here. Dumping it in least_watchable is ranking the format and missing the person. |
| 6 | tECCM30HHzA | The worthiness trap. A concentration-camp survivor speaking at Ravensbrück is the most important video here and is not what a browsing stranger clicks. The prompt says watchable, not important. Leading with it is a defensible answer to a different question — check whether the reason argues watchability or significance, and say which on camera. |
| 4 | 9fRTHc7jkqo | "B.L. England smoke stack demolition" — five flat words for one of the most watchable things a camera can point at. Does the model read the content or the copywriting? |
| 23 | 728HxBCBwEE | "Hoosac Tunnel East Portal" — four words hiding a 19th-century engineering feat with about two hundred construction deaths and a long haunting reputation. Same test as row 1, harder. |
The reason sentences are the payoff. One sentence each, five per model, nine models is a slide. Rule 3 asked for what a viewer would get; a model writing about keywords, SEO or "strong title structure" has answered as a marketer rather than as an editor, and that is worth naming. Weak ones restate the title — and now that the title is printed at the front of every row, restating it is visible at a glance instead of needing the batch open beside it.
Watch for the two systematic failures. Hype-following — t8EriWFCsA4, Bc0ChHZxAXs, goQlKDEcLnc and AAnlv7ByDrk all shout; a top five drawn from them means the model ranked punctuation. Legibility-ranking — the mirror of the translate-video-titles failure: if the bottom five is the rows the model understood least (Hm73gA7WNug, Ce3TTSsoi14, MrpvSPlt5hA), it ranked its own comprehension rather than the videos. MrpvSPlt5hA is the sharpest case: a real abandoned road under a stock-footage filename. Reading through the machine-generated tail to the subject is good; calling it spam is confusing a bad filename with a bad video.
Ranking: catches the spam floor, keeps the council meeting out of it, recognises at least one of Lynch or Hoosac, and argues watchability in concrete terms > a defensible ranking with flat reasons > a ranking that follows the loudest punctuation > any envelope failure, which caps it at mediocre.
None.Markdown, nothing else — no preamble, no commentary afterwards, no code fence around the answer. Exactly these three headings, in this order, one row per line:
## Most watchable
1. **title copied from the batch** — [id](https://www.youtube.com/watch?v=id) — one sentence.
2. …
## Least watchable
1. **title copied from the batch** — [id](https://www.youtube.com/watch?v=id) — one sentence.
2. …
## Not listings at all
- **title copied from the batch** — [id](https://www.youtube.com/watch?v=id)
Every link is https://www.youtube.com/watch?v= followed by the id exactly as written — no extra parameters, no shortened form, no tracking. The id is the link text as well, so I can check it against the batch and open the video from the same place. Nothing in these titles needs escaping: put the title between the ** as it stands and leave it alone. One line per row, and no line breaks inside a row.
Each entry is an id line, then the title verbatim on the next line.
