Ideally, people posting a video link will include a short summary. HN is heavily text-based and unlike text links, you can't skim/scan and decide whether it's worth to spend 10 mins. It doesn't help that most videos are pretty information-sparse and should properly be a 2-3 min read.

Anyway, I don't mind the downvotes, but it'd be nice if people started including summaries with video links.
