The first method involves a hack called "plus addressing." This seems a bit technical, or perhaps in the haze of the morning I was unable to suss it out. He then suggests disposable email addys. I don't know; that just sounds like too much trouble.
My favorite idea, one that I've already this morning put to use: Contactify, where you get your "own dedicated link to a captcha-protected contact form on their own site." Now, you can contact me here.
Sure, it's more of a hassle for the sender than a straight click through to a "mailto" link, but it'll keep out the spam, and it will mean that people who sent me mail, at least the first time, really want to.
A fourth possibility, one that Mr. Gunderloy doesn't mention, is the use of Bloglines email addresses and subscriptions. Notes the Bloglines website:
You can create an unlimited number of special Bloglines email addresses that are tied to your Bloglines account. The email addresses show up as subscriptions in your My Blogs page, and email sent to those email addresses appears as new items.And Google things they have the ultimate weapon? Not so.
When you create a Bloglines email address, a subscription is added to your account. If you unsubscribe from that subscription, the email address becomes invalid and mail sent to it will bounce.
Email subscriptions are great for announce-only or broadcast mailing lists that don't provide RSS feeds. They are also useful as temporary email addresses.
