Voice just goes to show that there will always be competition. A single idea will be taken by many and they will try to do it better. I, however, like competition.
Coming to it's success; it is relatively unknown. Compared to steem, they do not have a community as strong or driven to follow that niche. They will need a huge user base to get it rolling, which may rise from within the EOS community or from steemians looking to branch out. All in all, it is a good thing for blockchain based technology and the cryptoverse. I wish them good luck and time will tell how voice turns out
