I think OCD isn't the first curation project around but it definitely is one of the most well established and respected one. The team of 30+ curators from around the world covers all bases on Hive everyday, from first post from brand new accounts to under rewarded established users, to ensure we get to as many posts as possible.
Whilst I can't speak for OCD or acidyo, as an OCD curator, and for those interested to know, I can say that our curation principle focuses on original quality content from under rewarded users who believe in the longevity of Hive, and are active and committed to it, over those who choose to jump across chains to collect dust rewards.
Whilst we can't curate everyone everyday, we do try very hard!!!
There was Curie too back at the startish, but not sure what they are doing these days.
Ha! These are funny people. They think they are smart and it will do them well, - very, very few do well like this.
I don't doubt the same would happen with ocd if I and some other early members left it.
