If you're going to make a post to use.perl.org to game search engine optimization, you have to actually say something like "I like Perl programming", or "I enjoy programming in Perl". Or maybe, I don't know, have some real content about programming Perl, why you program Perl, why programming Perl makes your job easier, how programming Perl saved you a lot of money, or how programming Perl let you finish before the project deadline. Why waste time optimizing Google for a bunch of script kiddies reinventing stupid web applications who don't care what you think anyway?
Of course, the next trick is to get everyone to link to your Perl blog, so you need to set up new planets to constantly replicate every post multiple times. One Planet Perl aggregating Perl blog posts about Perl programming isn't enough. Set up several. Everyone can have their own. Get those links out there.
Now that you have that out of the way, you need to add your comment spam to every one of the top blogs in the search results so you get more links to your favored Perl blogs. I like Tim Bunce's Perl blog, even though it's mostly not about Perl and mostly about why advocating anything is fraught with peril and usually full of lies and personal agendas.
Of course, this is just as bad as what everyone else does and why search engines suck so hard now. With the flood of information whose only purpose is to affect search engines rankings, it's tougher to find any real information without some serious keyword kung fu. I guess it's fine when our group does it though, because we are us and they are them.
