London, Nov 14 (IANS) Social networking site Facebook may announce its e-mail service as early as Monday, if online buzz is to be believed.

The announcement of ‘Project Titan’ could see ‘@facebook.com’ e-mail addresses being unveiled, an overhaul of the site’s entire messaging system.

No British event is planned, however, so it seems that the so-called ‘Gmail killer’ may have a limited launch, if at all.

TechCrunch has reported that the product may be limited at launch, while pointing to the significant potential of a service that integrates e-mail with Facebook’s popular places, photos and events applications, reports the Telegraph.

Unusually, Facebook has chosen not to use its Palo Alto headquarters for the launch. Instead, the event may be held at Web 2.0 Summit in San Francisco.

According to social media news blog Mashable, Facebook’s current messaging system is ‘difficult to manage. Users are unable to send messages outside of Facebook, and the system can’t handle simple things like attachments and forwarding’.

‘If Facebook really wants to take on Google, it needs to have a far more robust messaging system, akin to web-based e-mail. Monday may be the day we see that happen.’

Project Titan was first mentioned by Michael Arrington on TechCrunch in February. It has not, however, received any official confirmation from Facebook yet.
