Since it's a hype machine I doubt it, but it's possible. Mostly, I think it is a case of:
We must do something.
Product Hunt is something.
Therefore, we must do it.I really like the collections feature - but I wish you could do a reverse collection search e.g Click on a Product and see what collections it appears in
I can't recommend enough the book Don't Make Me Think.
As a list of resources I think it's great. Often, I've never heard of any day to day new items on there. Some are interesting, some I have no need for and some I could use some day.
I can't speak to being on there as a company but as I said above - I've never heard of or seen so much of what gets submitted to it - it could help get the word out.
Unaffiliated people are prevented from commenting, meaning that every posting has a flood of positive, and completely useless comments.
Great site for astroturf, terrible for actually vetting a product.
