1) The anonymous color scheme is lame, so sending new people here who aren't logged in causes headaches. This could be fixed, but it's there to be a bit irritating so new people register.

2) Liking a site on social media is pretty lame, unless it's addressing a specific need at a specific time to specific people. Otherwise it looks like marketing, and we only need a smidge, and we get most of that from Google and word of mouth, I think.

3) There are very few places to get the kind of interaction we have here in the monastery. Stack Overflow is close, but they have too many rules, prioritizing accuracy over participation. (What? I can't vote because I haven't contributed sufficiently? Lurkers get no respect.) If there's something to share, share the node link. Which you can do with the free nodelet hacks mentioned. I wouldn't mind seeing one for G+, but then, I didn't really want my G+ account associated with my perlmonks account. So I'd just share the link, probably summarize the content for the tl;dr crowd, and be done.

BTW, some people try to ask questions on LinkedIn groups. Not very effective, as not many people pay attention to that. Questions go unanswered, or answered poorly, for days and days. And since everyone "knows" everyone else, sometimes the urge to be nice gets in the way of a much needed "WTF are you doing that for?"

4) FB and other sites are typically used in a "friend zone", such that only friends can see your posts. But good content should have wider availability. And it's often annoying to wade through the cat videos and aphorisms to find the technical content you want. You don't go any old coffee shop for advice on building nuclear power plants, why would you go to any old social medai site to read about Perl? Sure, there are special coffee shops and special zones on social media that may apply, but it may take a long time to find them, and they popup and disappear at a whim. Perlmonks has been here (takes off shoes...) a long time.
