I think it's not so much the individual launches that annoy people as the fact that there are so many at once. It throws off the usual mix on the frontpage.
This is what annoys me the most, especially if it's a 'stealth' idea or it's a YC company that posts once a month instead of using the "Who's Hiring?" thread.
The only thing I don't like about job posts is if they don't say right in the headline their geographical area. If they do have that, I can filter them out in 5 seconds.
80+ team in this batch alone,more from the previous batches as well.News about YC companies and job postings in a seperate page would be awesome on Hackernews something like xxx.ycombinator.com.A seperate page for YC startups to share their news and job postings. Should be easy for everyone to take note on whats happening in the YC family :)
I've wondered about this too. The conspiracy theorist in me came up with some silly ideas. But, in reality my guess is that people associated with YC (alumni, friends, YC co. employees, investors, etc.) vote up posts about launches as part of rooting for & supporting each other. Of course, many people associated w/ YC visit the site so it's almost an automatic front page.
