This is completely shameless. Several of the commenters here, such as "onewong", are sock puppet accounts for the company. See him/her previously giving "good job!" type comments to esharef (the founder). Other account with a similar comment created just for this post. A Y Combinator company manipulating HN with shill accounts? Really?

Yep, it's embarrassing and really unnecessary as HireArt sounds like a good idea and appears to be well executed. If you look back at many of their posts, there's at least one newly created account and a few reused accounts adding very little to the conversation, just espousing the company.
