Other than sending your e−mail address to a zillion companies, the best way to go about getting lots of e−mail is to have your email address appear on a webpage somewhere on the web. The reason is the spammers write programs to read every page on the web, save every e−mail address they find and then send junk mail to those addresses.
I get quite a bit of it and really, the only place my e−mail address is on the web that I know of is my website. So, I removed it. Now when you click "e−mail me" you get form you can fill out. That has the advantage that it can be used from anywhere where as the mailto:firstname.lastname@example.org style of link requires that the user be on a computer that has an e−mail program installed. It also has the advantage that my e−mail address does not appear on my page to be scanned by a spammer's program.
The other thing I did recently is I added "What You See Is What You Get" editing to my comments system. Supposedly if you are running IE5.5 or better you'll get a toolbar at the top of the window with icons for setting bold, italic, outlines, indenting, font, color, size etc. I'm sure there will be a few problems to iron out but it was fun to figure out how to get it to work.
