It's not snarky. How many times do I have to say that it's standard practice on HN to put the year in the title of article submissions? There are literally 4 examples of this just on the HN front page right now, 2 of them from 2021:

Typically when someone notes the article year in a comment — which happens all the time — the year is added to the title of the submission, either by the submitter or a HN moderator (who are the only ones with the ability to edit the title), without complaint. These complaints here are really out of line.

spacemanmatt, you joined Hacker News 9 years ago, and you have a lot of upvotes, which means not only that you have been helpful but that you have been here thousands of times.

So I am mystified by your comments. On the first page of Hacker News right now are seven submissions with a year at the end. It is standard practice to tag a submission with the year if it isn't this year. This is regardless of relevance. If it is on Hacker News, it is assumed to be relevant in some way. Else why would someone post it? If someone posted an article from 1888, they must think it relevant in some way.

Putting the year at the end has absolutely zero bearing on whether we think it is relevant. To me it is just another piece of metadata, like tagging videos, PDFs, polls, etc.
