For quite some time now, the buzz among Facebook employees about a supposed GMail Killer has been evident. A lot of discussions followed on tech blogs and forums. The project was supposedly codenamed as Project Titan, and was touted to be an e-mail solution which would offer a new way of communication to Facebook users, thus encouraging them to ditch their GMail (and other) email accounts. The hype increased when Facebook announced that it would be conducting a private meeting to announce something special. The announcement was made, and it wasn’t exactly a killer. In fact, it wasn’t anything remotely exciting. It was a revamped version of Facebook Messages.
