subject: Aliases shouldn't just be for spies!

Dear GOOGLE Geeks (I mean that affectionately),
I think gmail should allow the use of an email 'alias'. Of course everyone knows that users all over the world tend to create multiple email accounts with different cute little names, in the attempt to get more storage space and have the coolest handles. But because none of those accounts are consolidated, they pretty much go to waste a lot of time as a result as nobody really wants to sign into 8 different email accounts a day. However, if people are allowed to have one account, but tag it with two, maybe even three different names, or, "aliases", I believe it would make Googlers incredibly happy.
1. They won't have to log into multiple accounts and worry about multiple passwords and expiring usage rights.
2. They'll be able to have a work and personal account that are actually the same thing. The outgoing email could even attach the corresponding email address in it's replies, this way, the recipient is none the wiser.
3. It potentially saves you guys countless terabytes of space, which allows you to give more space to end-users.
Heck, even existing accounts could have a feature to "meld" accounts in the event somebody already has more than one gmail account.
I don't know, but I think that idea is gold. In fact, it totally rocks! I should have like a commercial where I get to expound upon how google takes customer suggestions seriously; how google allows the customer to make their google experience better as a result. Just thinking...
