Good points. You are right about being able to consume before registering. We added some popular users on the homepage to help out with that, we'll add a feed for popular/latest posts as well.

I have an account on Howl, its http://www.howl.com/cory

There is a search actually, but you currently need to be logged in to use it. I think we can port that to our homepage as well, along with the leaderboard so its accessible to everyone. Thanks for the tips!
