Yeah, I was thinking the same thing - I mean, you always see these great innovations on Steem - like a few weeks back, or maybe a month there was an archival services - where you could time stamp documents etc., I was amazed by it and was going to do a story about it, but forgot at the time- I have no doubt, that maybe one day there will be a blockchain version of Dessenter - yeah, you raise some good points about spam links etc., and stuff like that - regarding comments on user profiles - yeah, I think you can comment on anything at all - you have to have a gab account though - but it will only show up on the URL from Dessenter, so far as I have learned - there might be a whole lot more to it, I am only just playing around with it at the moment :/
