Yahoo's YMail - Don't Really Get It

They'll get an incremental number of new users -- no amount to write home about or worthy of even a PR, IMO. IF the cost to setup/maintain the accounts for these new domains(eg infrastructure, support staff, etc.) is relatively small then why not roll it out? Cost-benefit probably MIGHT make sense. Their probably piggybacking on existing infrastructure and support staff anyway so it's near trivial.

The potential for this will be WHAT services/features does that new customer(and a current one) get once they're convinced to sign up for a new email addy? This is what'll create loyalty, increase usage(time at site = more ad revenue) and grow the base.

Overall, though, I have little faith that this'll turn into anything like that at all. And it's a pretty big pain to switch addresses(if you have more than 2 friends/associates).

But, heck, why not?!
