PRO: Created the online metaverse Second Life, allowing users to interact with each other in a virtual world using digital avatars, which as of last month reached 5 million users with a virtual economy of $1.65 million per day.

CON: The site is riddled with problems, from technical glitches to vulnerability to content (users and critics have complained that the avatars are able to engage in sexual and gambling activities).
