>>I would presume the feature is designed to get people to log onto IHub that might not otherwise be on it.
Bingo.
Initially, this is the group it's focused on.
The iHub Junkies, this function will be of little/no use. This is designed for the person who's logging in not-as-often. We want to make them a junkie by getting them to log in and replying more often. :)
Myself, I'll never turn it on. My Blackberry wouldn't let me sleep and it would go off enough to actually start making music with the beeps.
Like I said, though, it's the foundation for some future features as well - that us Junkies WILL want it for....
