While I do appreciate your effort and tool, I can not but add one remark!
Why only focusing on the @ocd curation trail! I know lots of Steemains who do write more then decent posts without getting a visit from @ocd. Just because the topic their writing about is not a topic which attracts the curators of @ocd! I can mainly be found on sports related posts, but I am not neglicting other niches of the Steem blockchain! I even support all of them because the more niches we have on here, the more people will feel at home, the less the burn rate will be!
Don't get me wrong, I really do appreciate what your are trying to do, just like I do appreciate what @ocd and for instance @curie is doing. But there are more great post about niches about which the curators don't have any passion with and accordingly don't visit! You are wiping out all of these authors within your roulette. That's why I won't be using it!

Cheers,
Peter
