There seems to have been an explosion of carnivals since the last time I browsed the Blog Carnival Index. If you haven’t seen a carnival before, it is a group that arranges for people to collect and link to posts on a particular theme on a weekly or monthly basis. It’s hard to imagine you won’t find something to interest you if you scan through their listings. Just now I lost myself in the latest entries from the Books Carnival, the Carnival of Chocolate, and the Carnival of Game Production. Carnivals seem to come and go, but they’re an interesting halfway point between a portal and social bookmarking.
