Steem made several major errors in design, marketing, and launch/distribution. The original will not be the best.

I think it is based on Graphene, so the same DPoS consensus for the blockchain. I haven't looked in much more detail beyond that. I read they were offer rewards via voting, which IMO was one of the major blunders of Steem.
I heard Dan Larimer is working on improving Graphene and launching a new thing. So Ark and Steem will be using an inferior technology.
Sorry, my original is always the best comment was sarcasm, but sarcasm is hard to get over the internet should have written {sarc} afterwards.
Monero is not the original ring sig crypto but its overtaken whatever was the first one.
I'll forward your thoughts on Ark.io to the person I know who was thinking of buying it. Whether they pay any attention or not is up to them.
Also yesterday or the day before I sent you a PM you still haven't replied to you might not have seen it
