I personally see more of a need for centralizing the Clojure Blogs/News/Articles (i.e. your blog entries have helped me more than any wiki). The real problem is sifting through the Google Group or Google searches. It's tedious. So I can't help but think creating a site like hackernews or the arc forum would be a huge benefit to the Clojure community. Having a centralized location for blogs with a voting system and a currency stemming front page would be a big deal to me.

I'm short on time these days, but as a side project I am about 80% done creating one fully developed in Clojure. I suppose I could have just used the arc code, but that felt wrong. So if no one else beats me to it I will pitch it out there. It may take a few months for me to get around to finishing though.
