Clayop has also posted about DPOS (delegated proof of stake, for example Steem) and whether or not it is feasible for the average user to intelligently manage 30 witness votes.
You know I have to agree with him on that one,. There are so many variables involved in picking the right witnesses!
Tell me about it...
After all, I had to write like...50 articles...to try and scratch the surface on this topic.
I'm currently rethinking how I will manage my 30 witness votes responsibly. I currently only use 13 of them and I don't really have the time to evaluate any more right now. I'm currently toying with dividing up my witness votes into categories I feel are important and then look for witnesses that fill those spots. There's also a few community projects that I might offer a witness vote or two to. I do have a monthly recurring task to review all my witness votes.
