There’s Trackback, Pingback, and others, and there are even people who say they just don’t care.
So far I’ve implemented ‘Get Back!’ which is short for ‘Get back to me…’ which is a form you can fill out. This form will send an email to me, and I’ll read it. If it’s interesting enough I’ll Get Back! to you, or even post something about it here.
It doesn’t use some fancy new format that takes weeks to understand. Maybe version 2.0 will implement such complexities…
To respond to this post, just use our ‘Get Back!’ interface… (Warning: Human involvement required!)
