"Skype clearly believes that developers (and the awesome new services they build which will require Skype) will be key to bringing in new users. The pressure to grow may also be behind Skype’s decision to add XMPP support to the most recent beta version of its Windows client, letting it interoperate with other IM networks. Skype needs to grow especially as it faces more competition from Facebook, Google, Apple and any number of other companies building out video conferencing and chatting capabilities into their services and devices." - LANjackal
