I've done my semi-annual bitch at Perlmonks for not reporting bugs. Here's the last one and my personal favorite, the Ungrateful Fucks speech. These usually occur after I find out, third hand and three weeks later, that there was a big discussion on PM about some major bug or another in my code and nobody thought to tell me.
I will now take me own advice. Bitching is not doing. I have bitched, now I will do. The problem is Perlmonks folks forgetting that many CPAN authors do not read Perlmonks and so never see their complaints. Even if they do read it, complaints are easily lost in a twisty maze of replies that each individual author does not have the time to search over and over again.
A solution? Perhaps somewhere on the posting page can be a simple "are you writing about a bug in a CPAN module? Why don't you send a bug report about it?" with a link to RT. It could even get fancy and give you a single textarea box to type in the module's name and send you straight to their RT page.
