I was thinking, earlier today, about how I hate having to use my e-mail address to register for things. Sure, they say they won't use it for anything untoward, but if they were planning on selling it to 12-year-old Nigerian spam-lords, do you really think they'd tell you about it first? No, of course not. Setting up an auxilary e-mail wouldn't do much more good, because eventually it would just get so clogged up with spam that it would be useless. So the ideal situation would be to have a disposable e-mail address, that could be set up with a minimum of fuss, and then easily deleted once it had outlived its usefulness.
Enter Guerilla Mail.
Direct from the website:
Guerrilla Mail provides you with disposable e-mail addresses which expire after 15 minutes. You can read and reply to e-mails that are sent to the temporary e-mail address within the given time frame.This is pure genius. Awesomeness on a level unheard of by man or Batman. Sheer intellectual perfection unheard of since the invention of sliced bread.
This, my friends, is zero-cool.
