I don't think I have any fondness for either. Kind of missed the train when they were still hip, and only use them because I have to.

But I'm already writing a eulogy for Skype. Skype is a zombie. The current offering is wearing the skin of Skype, the real deal was P2P.

I still use Skype heavily for group chat with friends (we have a chat thread that's not missed a day since 2010, and has people joining and leaving every year) and videocalls (my family is spread across the continent). But I fear that a stray update could take the functionality I need away. With how MS kills their products, it can just happen one day.
