This is a big deal for me, I played with Skype back in the day, but never really used it much since it required a second client, and I have always used Gaim (which is now Pidgin) to consolidate all of my accounts into one client and didn’t want to break out of that mold, but now I don’t have to.  Using the Skype API, Eion Robb has created a Pidgin plugin called Skype API plugin for Pidgin/libpurple/Adium.  Now I just add my user to the Pidgin accounts tab and I can now chat via Skype in Pidgin just like I chat with all my other contacts.  Note that you can’t do the video of Skype on Pidgin.  Mac users note that you can use this on Adium (my fav OS X chat client), which uses libpurple, which is the backend for Pidgin, on Mac.  So now I’m using Skype again, which is a propreitary app, thanks to them providing an API for the Open Source community to latch on to.  Ah, the circle of life…
