OK, I'll bite and ask. What's the catch in all this? Nothing's free... especially online. Their model looks like one that starts free and eventually something changes... they want ads on sites, or they'll charge. Netzero was a good example of this.
But they aren't staffing their server room 24/7 for free, etc.
