Windows Live Hotmail offers temporary e-mail accounts

Microsoft has announced a new feature for Windows Live Hotmail that allows you to create and manage multiple e-mail aliases from a single account.

That's a cool feature which will surely get hotmail addresses banned on many sites.

I'm sorry but what's the novelty over what Yahoo Mail has been offering for years? Except that Y!M won't let you create alias accounts that include your original email element (a security issue appropriately raised in the article above)...

Or did I understand this wrong?
