Github Meets CPAN
When Olaf Alders was writing about expanding your MetaCPAN profile he suggested to build something interesting on top of the MetaCPAN API. When I started writing Pithub I did not have any use case in mind at all. I just wrote it because I was bored and because there was no Perl support yet for the v3 of the Github API. When I read Olaf's article, I got an idea: Connect the CPAN authors listed by the MetaCPAN API to their Github data, in case they have their Github account set. And there it was: The first use case for Pithub.
The whole thing was kind of boring until Olaf had yet another great idea: Add some ranking there and sort the users by it, instead of sorting them just alphabetically. Currently the rank is calculated by this formula:
(count of your followers) + (sum of watchers of all of your repositories) + (sum of forks of all of your repositories) = rank
