It looks like Facebook's messaging system is about to get a long-awaited overhaul — possibly the rumored Project Titan of earlier this year.
Mashable has received invitations for a press event Monday.
Unlike previous Facebook events, this one takes place in San Francisco. The company chose not to have the event at its headquarters in Palo Alto due to the Web 2.0 Summit, where Zuckerberg will be speaking. The announcement will take place just a few blocks from Web 2.0 at Moscone Center in San Francisco.
The invitations we received prominently display the inbox icon used in the company's iPhone and Androidapps. That's why we believe this event will almost certainly be about a revamping of Facebook's messaging and inbox system.
In our opinion, the current Facebook messaging system is broken. It 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.
