I realized after posting that my initial reply may have sounded snarky, and that wasn't my intention. I'm a cross country and track coach, and the reality is that, like it or not, part of my job is ensuring the team has a visible social media presence. I feel an obligation to at least attempt to stay on top of what services people are using the most at any given time.

Absolutely, yes. I almost always try the newest networks/apps because I like to see for myself whether I think they're going to be a hit and/or worthwhile.
