Well, it's happened again. Someone commented on one of my fifty websites, I responded quite innocently, and damned if they haven't slapped me on their newsletter mailing list. One that has no "how to unsubscribe" link on it.
PEOPLE! It is NOT COOL to start sending someone your newsletter unless they indicate they wanted to subscribe. Put a newsletter link on your website and the most you should do is send them an email with your URL and allow them to decide whether or not they want your mail.
If you DO send out newsletters to everyone and their mother, for Pete freaking sake, include an unsubscribe link.
Sending people unsolicited newsletters smacks of desperation. And it's a sure way of turning people off to what you have to say.
