I used to do three. TE, a mountain biking site for our state and trifuel. Trifuel was rendered silent by FB. The mt bike site is up and running full throttle.

I think TE has quieted down a lot the past two years, my guess is FB and twitter. My husband and I do not do any other social media. We both teach high school and are am SO turned off by it. I am sure it is great for some folks, but I see nothing but problems from the students and LOTS of the adults. We keep in touch with our friends and loved ones the old fashioned way....email and the phone. And I am no good at small talk either!
