VOTE!https://www.poloniex.com/votingLast thing we want is having OEC at the top and Dev without a block explorer yet, without a block explorer this coin will have a hard time getting listed.
Regarding the block explorer, the best and easiest way would be to try to get OEC added to
Minergate. They'll provide block explorer and it would also increase visibility and hash rate, since they are currently probably the best cryptonote pool IMHO.
