The Perfect Social Media Trifecta

I've been reading blog posts about making the most of social networking sites and plan to report on a few of them here. I hope that those of you who aren't already much more tuned in to them than I am may find something of interest in the sites I mention. One of the best posts I've seen so far is The Perfect Social Media Trifecta: Have you found yours? on GrayMatter Minute, a blog by Renee Lemley. Quote from the About page: "Ready or not, social media is here to stay. And so we need to study it, understand it and learn how best to use it to support our ... objectives." The trifecta referred to is Facebook, LinkedIn, and Twitter. I'm on the first two, and am likely to soon join the third. That blog, and others (not counting the "plane landing in the Hudson River" episode), are making me aware of Twitter's possibilities (from a "what's in it for me?" perspective).
