At this point I'm assuming that you have my email address. If not, find me on Facebook or something. There's a link from my ClaimID profile.
You can probably also figure it my email address on your own. You know that my name is Matt. You also know that I'm at pearsonoid.com. It should be easy enough now. My IM handles are won't be posted here though. Sorry.
This is the stuff you need to positively verify that I am who I say I am if we exchange email or instant messages. It can also facilitate the exchange of secure communications as well. This is a good thing.
For the curious, there is more information about PGP available all over the Internet. Below is my PGP information.
