A lot of this right now seems to wind up in Meditations (or sometimes Cool Uses for Perl and Announcements). There might be a benefit to differentiating between insights about Perl programming ("this is an interesting technique I discovered") and insights about Perl ("Perl is really cool, helps me code quickly, and I love it"). That said, as responses to my post New section for Regex Q's? suggest, there's a lot of legitimate concern about too much fragmentation. The volume of advocacy posts is sufficiently low that I don't know that it's really a problem right now. (Maybe the lack of advocacy is a problem, but that's a whole separate story.)
