This sounds like a niche that is waiting to be filled, and it is kind of exciting. But you should take this with a grain of salt. The audience on HN is probably quite skewed in your favor, geeks and hustlers who are predisposed to using something like this. I remember LinkedIn for a long time was primarily used in the tech industry.

That said, I like the simple design of the page, and I think it has a fine balance of seriousness and youth. I am going to look at your internal pages, and will give you some more feedback.

Meta: I bet a decision like that took a lot of guts. Congrats, you are no longer at step 0.
