Could Facebook and Google become competitors soon? Aside from getting a new facelift to commemorate its 6th birthday, a recent report hints that Facebook might be gearing up to provide its own full webmail service, which will obviously have to take on the giants such as Gmail, Hotmail and Yahoo mail. If the report is accurate, the webmail service will make use of your Facebook vanity URL, so if your vanity URL is johndoe, you’ll get johndoe@facebook.com. This would be a significant departure from the current messaging service that it’s offering, and if Facebook really does roll out a webmail service with full POP/IMAP support, it will certainly be interesting to see how it matches up to the competition, with some folks even dubbing it a “Gmail killer”.
