Here's a description of what Perl Buzz includes, from the launch announcement:
The main Perl Buzz blog, which you're reading right now, is all about news, reviews, and what's exciting in the Perl world. We're interested in everything from impressive Perl websites (see our review of iusethis.com) to releases of free and commercial Perl software (like Movable Type 4.0, released last week) to interesting uses of Perl you might not know about (like attributes or how to write a LOLCODE parser using Parse::RecDescent).
Over in Project Hum, we track what's going on in Perl projects. Anything from performance tweaks to calls for help to translations of docs into other languages. We watch other Perl news sources to find out what's going on, but please let us know if you'd like us to post something about your project!
CPAN Watch is all about what's noteworthy on CPAN. Watching the full feed of CPAN uploads can be like drinking from the firehose, so we filter it and just post the most interesting releases, along with why you should care.
Check it out and, if you're that way inclined, digg it.
