I’m on YouTube in two different places:  ChristopherMast is my more “thought out” video channel.  NotChristopherMast is my video blogging outlet, with more “off the cuff” stuff… now including iPhone videos, apparenty.  We’ll see where my brain takes me…

Of course I’m on Twitter! Who isn’t? You can follow me there (or not, I sincerely don’t care). If you’re witty or interesting, I’ll follow you. If you post messages of personal despair or constant banal FourSquare updates, probably not. Two things you should have guessed by now; I don’t use FourSquare and my username for Twitter is “ChristopherMast.” I DO however, have a secondary account that I rarely update called “DoomedChildhood.” All the updates are quirky things I remember from when I was a kid. I’m not sure if I’ll start posting there again or not.

I just joined Instagram, and I have found I like its ease of use so much that I replaced my Dailybooth widget on this site with an Instagram widget. It’s “iPhone only,” but it you want to check it out, get it at the app store or at Instagr.am. My username there is “ChristopherMast.”

Have an iPhone, iPod Touch, iPad, or a Droid?  Play Words With Friends with me!  It’s basically Scrabble with just a few variations on the board (I’m guessing to avoid copyright or patent issues).  My username is “ChristopherMast”

I just joined Tumblr. I’m not even really sure what I’m going to use it for. We’ll see. Follow if you’d like, but I’m going to have my Tumblr feed post to Facebook and Twitter simultaneously anyway.

I like experimenting with DSLR photography, so there’s hardly anything on my Flickr page yet, but I’m having fun with it.  Somehow, the username ChristopherMast was already taken.  I don’t know if it’s a different Christopher Mast, or if I set it up originally and didn’t use a normal email or something.  So, there, I’m THEChristopherMast, under flickr.com/photos/christophermast.

I’ve been on Yelp for quite a while, but only recently have I started actually using it. My reviews at the moment are for San Francisco and Oakland area places, but I might add some for other locations soon. ChristopherMast.Yelp.com

Sometimes I go to Digg, but not on a regular basis… it’s kinda like reading a magazine. As you might have already guessed, my username there is “ChristopherMast“
