The Digital Inspiration blog points out a Gmail trick that can be very useful for blocking spam. Everyone who has an "firstname.lastname@example.org" address can also receive mail sent to "email@example.com." What's the big deal? Well, knowing this gives you a stronger hand when you fight against spam, bacn, and all that other not-so-important but distracting email. Try giving out one or the other addresses to important, close contacts, while using the other for all the other stuff.
