Pros: Freeware/open source; handles a wide range of IM services, both major and minor; frequent updates
Cons: Subject to changes in the proprietary APIs of IM networks such as AOL and Yahoo! that could lead to temporary inability to connect to these networks, free and open source status begs question of Gaim's long-term availability (continued development depends on continued interest of programmers)
