SciFi.com has started posting a series of ten Battlestar Galactica webisodes briding the gap between the end of last season and the premiere of this one. The first one is pretty cool, and feels very much like part of the series. However, if you haven't seen the end of the second season yet (I know at least one friend has not), I'd recommend staying away until you're all caught up. Otherwise, there will obviously be spoilers.
