I care about Google rankings because if you look for perl+<whatever_keyword> in Google, chances are that you are never going to find the CPAN module(s) that would help you. Just try it (perl+cgi is quite scary ;--(. The current situation is that if you know CPAN and if you are ready to spend some time either here or on the newsgroups or in some mailing list, then you are going to use the right tool for the job. I would like to increase the likelihood for users who do not have that kind of time and who simply use Google to get to the same point.

So I think your objection is valid, but only up to a point: if you are looking for Tk::Frame, then the link I propose gives you Tk as the third result. If you know what you are looking, then chances are that you are going to find it. BTW Tk is an example where googling for tt>perl+tk takes you to the Perl/Tk site which looks like the right place to go.
