adding dimensionality to a cardboard cutout of a person.

Does anyone have any advice on which kinds of online stuff are mandatory if you're pretending to be an actual person who might be employable?

You can assume I have realname™ type email (which I do, with both Yahoo and Gmail and they're separate from where the DW people know me) but I don't belong to anything else. I could have G+ but I'm not likely to have any content there (and I didn't sign up because that made it a lot easier to make sure there were no accidents.) There's nothing I would share that wouldn't hurt me more than it would help at least in the long run.

I don't really want Facebook, but I'll sign up if it's required to be a person. I'm going to leave my content as empty as possible and make absolutely sure I only use it in a browser I never use for anything else so I won't be auto-sharing my personal business.

I know I need LinkedIn. *grimace*. Do I need Twitter?

How hard is Skype to use? My computer promises to have "free skype and video calls" and I did configure the Gchat to use video, although I've never used it. I only tried once with Corrvin who was on her way to work and not interested in flashing me.

What else am I missing? Tumblr? Pintrest?
