I don't know much about the setup, but I've seen the term witness vote proxy thrown around and I just assumed it meant something along the lines of following the witness votes of a certain account.
If in fact that is how it works, it might make sense to start something akin to political parties here.
Create an account that stands for x,y, and z and communicate that clearly and ask people to let them be their witness voting proxy. That way the little fish could start to make a difference.
On the Witness Page after the list of names you can set a proxy, I know at one time Inertia had a lot of people following his vote via proxy.
So, yeah, if a ground banded together and voted together they would have a lot of power.
Ahh, thanks for the info, it would be great if you could create a partial proxy, like let someone use x amounts of your witness votes and you control the rest.
