Social media - overwhelmed and feeling guilty

OK, Utecht, cut it out. I know I should be playing with Google+, but give me a break. I can't keep up with the social networks I have now.
I'm already feeling guilty that...
- 99% of the tweets I receive go by unread and I get to Twitter only a few times a week.
- I skim my GoogleReader, diving into only about 5% of posts.
- I haven't wished anyone happy birthday on Facebook for six months
- I've never had a single useful interaction with anyone on LinkedIn and turn down most requests for connections.
- My blogging is slipping.
- I can't keep up with the half dozen email lists to which I am subscribed.
- Our district is only just getting rolling with Edmodo this year.
- While I have had a Google+ account since they were first offered a year ago, I haven't done anything constructive with it - not even a Hangout.
- Don't even go there with Pininterest, FourSquare, Instagram, and the "social" components of YouTube, Slideshare, Delicious, and other Web2.0 tools.
And here's the scary thing. Unlike most of the young teachers here on staff, I don't really have much of a life outside my professional interests. I don't go to sporting events or watch TV. I don't have a young family that demands my attention. I don't have hobbies like woodworking or car restoring or cross-dressing. (Just wanted to see if you were paying attention.) I enjoy technology and learning new things, but for me this is all becoming overwhelming.
Jeff, I still value a graphic you created some years ago. Uh, it's this one:
Remember it?
Here's my question: Is the ability to select and discriminate among social networking tools a needed, teachable skill? Or should every tool be used by every teacher?
My thought is that when any pundit recommends a new tool, they be required to suggest a tool that is no longer useful.
So, buddy, what is getting less attention from you now that Google+ is getting more attention? I certainly hope it is not Ms Utecht or the Mariners.
