I'm nominating @dcooperation community, it's the community created by me and @tibfox, we create it to make people make more collaborations, we support all d-apps, but we upvote only @dtube 's videos to earn some reward and we use all the earning to power up @dcooperation account, all the upvotes are made manually. I personnally delegate almost all my power to that project, because I beleive that collaborations are very important.

Here is our best collaboration to promote dtube and steem blockchain on youtube :
