I have been interested in git for a while and played around with it a few times and past.
Yesterday I finally moved my two open source haXe libraries (hxJson2 and hxGD) to GitHub. (hxGD was hosted on Google Code before.) I really like the ideas of the work flow of git and seriously thinking about moving all my private Subversion repositories into git repositories, since there are well working tools to even import history and branches.
I am using different instant messager protocol. ICQ, IRC, sometimes MSN and Skype. It always bugged me to have 2 programs open. Pidgin for all protocols except Skype and Skype.
Today I found a really good working plug-in for Pidgin which allows you to use the most Skype features directly from Pidgin: http://code.google.com/p/skype4pidgin/
You still need Skype to be running, but you got all you contacts in you Pidgin list. If you make a call the standard Skype dialog appears, all message communication is done via the usual Pidgin conversation windows.
