We have the ability to share main and meta Questions or Answers.
The main Tridion StackExchange site also has "share to" options for:
How can we qualify for or request these buttons for the Meta site?
I was specifically looking to Tweet this question on promoting the site; I can of course copy and paste in the meantime. :-)
I checked 5 other meta sites (for non-beta stack exchange sites) and the only one with had a share box allowing direct sharing to Google+, Facebook and Twitter was meta stackoverflow:
meta stackoverflow is a 'special' meta site so this makes me think the type of sharing you are requesting might not be available on the meta SE sites. However, I think the best think to do is to probably flag this post as needs moderator attention so one of the SE community devs can chime in.
This is how all the child metas are set up (with the exception of meta.stackexchange.com). There's no 'setting' to enable it, so it would need a systemic change to make that happen.
I checked into why it was set up this way, and best I can gather is it's because the child meta posts are generally more geared towards people who are actively using the site. That makes it awkward to share this stuff broadly across the broader Internet, especially given that new visitors can't even meaningfully interact with a child meta.
But I don't particularly agree with the distinction —
We shouldn't assume that someone's audience, motivation, or need for sharing is wrong for this site. Bigger picture, folks become accustomed to how these tools should work, and when they don't work the way you'd expect, it makes for an unhappy, head-scratching experience. This isn't exactly a game-changing problem, but adding such exceptions in behavior between meta and the main Q&A should have a much greater impetus before justifying the inconsistency. I'm going to leave this a feature-request.
