There is always a room for improvement.

For example many Hivers don't take witness voting even seriously and don't vote at all. Some don't even know it exists. Or they are not voting for any proposals, that's also bad.

This way a lot of the things HIVE blockhain offers is still in hands of a very small minority that know about this stuff.

There should also be a witness voting decay.

So how to convince people to vote? I myself was thinking of creating a community witness that would share it's rewards. If you would vote for this witness and also 29 others, you would share the rewards or something like that. It's in the making. I will make a post about it later to know opinions of others.
