As of late, I've been getting multiple social network friend requests. I don't mind, but I need to emphasize these guidelines:
Please please please introduce yourself, tell me why you're adding me and that it was through the blog. I'm very very cautious about adding anyone I don't know (I have a brand to preserve) and it's just common courtesy. Facebook: It's unlikely I will add you as friend here unless you're an incoming student (and followed the above advice). This is a personal space. I'd much prefer if you added me on LinkedIn, again, with an introduction.
There's also my Twitter handle, @julianneharty but that will slowly transition to more video-game related postings than MBA things.
