Fast, simple and feature packed - Pidgin is one IM app to rule them all!
The usual path for Linux and Windows users that need to connect with others via XMPP (Jabber, for example) is Pidgin, a universal chat application that supports many protocols. Pidgin is a simple, open source tool with modest RAM usage and a wide selection of plug-ins that extend its functionality. The latter is down to Libpurple, the Pidgin backend. Thanks to its modular design you can collect several different types of IM accounts and use them all from the same single application. That sort of account aggregation puts Pidgin ahead of many of its rivals.
