I've finally jumped on the Skype bandwagon, though I'm not sure that I'm happy about it. I like the technology behind it, and it does fill a certain set of needs very well (in my case, I need it for work). But, the client is terrible. It's cluttered with buttons and features and labels and big shiny things. I'm having a bit of difficulty figuring out what it can and cannot do. In contrast, Google Talk, my preferred client, is clean, simple, and very easy to use. So, in the end, I'm now running both.
You can search for me on Skype either by my email, firstname.lastname@example.org, or by my account name, doctor_colin_smith. And as always, you can find me on Google Talk by my email.
