> Alias generation. I really would like to subscribe to some news letters or place my email out in public but I don't want to do it with my real email for fear of being spammed.

+1 for this.. I'd like to give out specific emails while filling forms and be able to deactivate/delete it as soon as i don't need it.

Fastmail can do this. You can also have wildcard handling, so that there's no extra step to create the masked alias.
