Honestly, I only use it for the convenience of being able to keep track of which row you're on (it took this pattern to introduce me to ribblr)! I had been jumping through hoops to make most of my PDF patterns like this in some way or another. I even dedicated my tablet to the process, so I wouldn't lose my place! (Well, that and comic books)

I've tried the social media aspect of that site, but I'm so far removed from the chatroom style of interaction that it just doesn't really appeal to me. Maybe that aspect is geared towards younger, hipper, more social people than me!
