I've been following their blog for a while at LibraryThing and so far it looks interesting. The basic premise is that you add the books you own/like (up to 200 for free, $10 a year or $25/life after that) - essentially very book centric bookmarking, then you get to leverage the combined libraries of other users to find books you might like. Amazon suggests titles when you look at a title - which is fun and sometimes interesting, this is about the same but perhaps lets you find things a bit more obscure. The tag cloud of authors is impressive! I saw quite a few SQL Server titles as part of the search too.

So do you go for a generic bookmarking service like Delicious, or split your interests across many niche sites like this one? I think the internet does a marvelous job of serving niche groups (even one as large as all books!), but I also like just having that information in one place regardless of niche. Call me undecided for now.

And as a bonus, looking for something to read that's non technical? Try David Gerrold, Orson Scott Card, Greg Rucka, William Bayer. All are reasonably mainstream if not as well known as Clancy and others. And though showing their age a bit, don't miss 21 terrific novels about Travis McGee if you're a Florida person.
