StormPost's Damian Borichevsky suggested that Facebook becoming an ISP faces challenges. The email address program is balky with: no subject lines for messages; messages getting stacked with the newest ones at the bottom; and a filtering mechanism that puts messages in filters if not sent from a friend.

Borichevsky said the system's current incarnation will make it tough to use it as a main ISP.

But, Facebook has shown it is constantly evolving and tweaking and improvement could come and likely will.

"They are a long way off in some areas," Borichevsky said. "Just the momentum they have with the sheer number of users puts them in a great position."
