another way to publish - SourceBeat

i was reading a talk with bruce snyder on Castor, Maven and some other Java stuff, and he plugged SourceBeat at the end of the article. it is an interesting concept: $30/book/year and often early access to chapters. this is similiar to the o'reilly safari model but perhaps slightly better because the content is more up-to-date. there is nothing in their library that interests me right now or perhaps i'd give it a shot.
