Interesting post on affiliate spamming on Twitter. Joel Comm is apparently asking his affiliates to post a Tweet which says "Get Adsense Secrets For Free!" with a link to his adsense book. And about 30 of them are doing this.
I think this is a TERRIBLE idea. I know I sound like a broken record saying this, but joining Twitter is like joining a local business person's networking group. Imagine you're a car salesman walking into a meeting of people you barely know and aggressively shoving a contract in front of people and asking them to sign it. They're going to flee in horror.
Now imagine letting them get to know what a great, honest, guy you are, and that way - when they're ready to buy a car, they'll want to buy from you.
twitter is just such a great tool, I hate to see people mis-use it.
