Steem voting needs to change then, to allow no time limit, not 24h, not 30d max. People can judge answers for all time, not just 24h or 30d.

This requires payouts to change as well.

And also comments need to change. You can't provide another answer after some time, as comments are disabled.

Otherwise, in terms of knowledge and answers, valuing answers, I would not use a system that limits to 24h or 30d for recognizing knolwedge about a question.

But great site! Way to go!
