I agree with Chibi. E-mail's important! I get so much school stuff through e-mail mostly tickets for sale as Husker football is srs bsns or requests for notes. Speaking of which, I had to send an e-mail with my essay for my teacher to use. XD; Apparently it was good. Funny, I thought it was crap.
I also get e-mails from Grandma, as it's a lot easier for her to e-mail me than send letters. I'm terrible at letter-writing. I really should send one to my other grandparents. And I don't have a phone (should next week if I get on it!), so it's not like I can call anyone right now. D: So e-mail helps me keep in touch with some of my family that I otherwise wouldn't talk to.
Now, you might be able to make an argument that paper mail is slowly getting outed by e-mail, but even that's really shaky. I don't think you can say IMs and forums are getting rid of e-mail at all. Maybe in this tiny slice of the Pokemon fandom, but not for the Web as a whole. o_O
