This has been on my radar too, but I was hoping the people listed on the Microblogging
page on the wiki were still doing things. But I'd been thinking about just what you
guys have--inquiring about whether they're still maintaining, etc.
A social-media mailing list may be in order, separate from the marketing list where we can
have those account admins join and as necessary send mail that says, "Please
faceplustweet this:" so it doesn't get lost in our general mktg list traffic.
