Shrug. I've asked a question on clpm once. I got a snippity reply from Abigail, and was scared off. That was a long time ago. But even though I don't ask questions much, I do post a fair bit here, and I've been on several mailing lists -- perl6-language and perl6-internals, most relevantly. I've even posted a couple times to p5p.

Sure, it's perfectly possible to be a good programmer and never post anywhere. But consider it one more way to follow up on your references.
