Please forgive my laziness, but I might be a good example of your target audience, and I didn't bother to login.
There are no companies or developers to browse, and I don't see the added value over, say, LinkedIn or Hacker News.
The current landing page suggests that I have to put in work, and I don't see what I might get back in return.
I don't mean to be harsh here, I'm just supplying a data point :)
