MetaFilter (
http://www.metafilter.com) is a
collaborative weblog.
In fact is something like /. but with less hassle and features: contributors point to news in the web, others weblogs, stories of all kind and comments. It nicely follows the current trend of weblogs and collaborative writing in the web, which is a very good thing.
As a tool for collectively improving MetaFilter, MetaTalk (http://metatalk.metafilter.com/) also offers a discussion area about MetaFilter itself and weblogs in general.
One think I like about MetaFilter is that is quite chaotic,
(note to self: beware, because is even more U.S.A oriented than Everything, specially now with the Bush - Gore comedy at full steam.)
and provides some interesting links and some
good connections with
things I didn't know until today.
