Skype is the home of the BZPS, the (replacement) chatroom for BZPC. After a time, most members migrated from Xat to Skype. The chat is often dead, but is considered the primary chat by most members. The QQQQ, Kothra, and Arby are some of those that HATE it, and QQQQ led a war against it.
The Skype is also very very dumb and sucks your brain.
Tenebrae Invictus would argue against this statement, as he uses Skype heavily, but his brain has been too sucked to provide a counterargument.
