I've been doing my writing first thing in the morning. That is about the only time of day I have any energy, as work has been really busy for the past couple months (if you don't understand the reference "ICD-10", count yourself fortunate).
And I have other sources of social energy besides NaNo. The writing classes, including a course following Julia Cameron's Artist Way got me going on morning pages. And the Twitter hashtag #WriteChain has continued that by giving me a place to keep accountable for my daily writing goals.
My main excuse, though, has been physical pain. Unless a quip is short enough that I can peck it out with a finger or short enough for my voice-to-text not to get lost mid-sentence then crap out on me, I don't post it much. Hence my continued presence on Facebook.
I might try doing a November blogging thing if there are folks still around here in LJ/DW land. Roll call?
