I use e-mails for initial communication about 50% of the time (when nothing else is available) but I highly prefer board-based communication and AIM to e-mail.
Mostly, my e-mail is a way station of sorts: I use it to get notification of posts to boards (which is REALLY helpful sometimes to me as a moderator on another board: day before yesterday, some trolls made the fatal error of posting their spam to a thread to which I was subscribed:
), to exchange fanfic chapters with Haibane Shadsie so we can co-write them, to contact people that have no other listed means of contact, and to send images when my webspace is down.
Not only does spam annoy me, but forwards and the generally cumbersome nature of e-mail also bother me.
EDITED to add: Madphil is right. Spam is dependent on where you give your address. My SassyHush Compuserve address (which I do my best to guard) only gets a few spams a month. My "bishiefangirl" yahoo address gets MUCH more, simply because I use it to register at games sites and because I used it to pull a prank on that fount of spam and ordination mill called the "Universal Life Church" (LOL, PM me if you want that story, it's a riot
) My new "fayequeenofhearts" mail.com address, which I use ONLY to bait spammers and scammers, will most likely get all spam all of the time. Or at least I hope it does-wasting the time of these Nigerian scammers is great fun. Hehe. ~.^
