So I haven't heard of it before now, but it seems like yet another pattern search and storage site, and the search function isn't as robust and deep as Ravelry's is. Though I am sorry for everyone who still can't use Ravelry and how they handled their redesign is unfortunate, I can't seem to right click and open a pattern on a new tab on Ribblr to check it out that way, which bugs me.

I find the "crafting revolution" tagline hilarious, especially since althea_valara mentioned Knit Companion, which has "join the knit revolution" tagline, and just.

So many fiber revolutions! So little time!

I use Ravelry if the patterns are posted there, or Etsy if they were there (sometimes they were), or personal sites, but I suppose if people post them to Ribblr and link them from their blogs, I'd use that. Just because Ravelry is the juggernaut doesn't mean it has always been the only site.
