Do not change anything in block reward voting, the point of a pseudo-democratic coin like heavycoin is to let the miners decide.
Changing the block reward will be like cheating to me.
I hate coin changing reward just to keep the value from decreasing. Let the market (and the miners for heavycoin) decides !

I am voting 1 myself since the beginning but I do not care that some people vote 1024.
They surely have a reason to do it and it should be respected.

The only things that will make the value grows up is hype and services.
