Part of my daily routine is to check the metacpan recent page. Often On occasion the majority of new releases (since the previous day) seem to me like they're only going to be of interest/use to the author. Over the years this all adds up, everyone needs a hobby I guess. When reading a post/chatterbox conversation when someone starts talking about putting their pet project on CPAN, more often than not I can see no valid reason anyone would have for using what they propose. This isn't to say that CPAN is 'complete', or that people shouldn't add stuff, but given the modern cpan installers can pull things directly from github that this could be a more suitable place to host some pet projects.
Update: slight rewording, strike out above.
Update 2: Related perl.com regularly publishes a curated list of what's new on cpan articles.
