Feedback For Privte Beta

We recently launched a private beta of Blogcastr (http://blogcastr.com). Blogcastr is a free, easy-to-use live blogging service for sharing cool stuff as it happens. We wanted to try to start getting feedback and I would love to hear what people think about it. The current design was meant to simply get something up, everything is in the process of being redesigned. If anyone would like to sign up "hackernews" can be used as the invite token. Thanks! -Matt
