I have been experimenting with different social sites over the past year, and below is an "official" list of where I have accounts. Some people have already name-squatted on "Dark Tangent" so sometimes I also use "The Dark Tangent". Also some of the anti-sec followers have tried to impersonate me on different social sites. If in doubt about one of my accounts, check here.

I post my articles and writings on my blog [] and am trying to do more with it. It isn't the best way to distribute my writing, but this acts as a repository.

I use LinkedIn [] for keeping a basic online resume. I don't link to everyone who asks, I try to make sure I have met in person, or know of you through friends before I accept an invite.

For purely social I am experimenting with a Facebook public profile [] as well as very rarely using my personal one []. NOTE: I haven't used Facebook in a couple years, and try and stay away from it.

For day to day random short messages I use Twitter [] and when talking about things related to DEF CON I use the hash tag #defcon, useful for when you do twitter searches to see what people are saying about DEF CON.
