Automatically add a signature to your Facebook posts
fsignature.comGreat, just what we need. Nothing like recreating the worst idea of cellphone text messages, but for Facebook.
:) Fair, but think of this scenario: you are supporting a cause but you don't want to spam your friends by reminding it all the time. A signature is a good use case in this situation, you can post something of value to your friends and add a small notice about the cause you're supporting.
To be honest, I'd just unfriend anybody who used something like this.
