Isn't the possibility to allocate funds itself already a big enough incentive to vote? Currently with many big accounts not using their voting power, effectively you get nearly twice your money to distribute to good content of your choice. What do you want more?
Currently many people are just voting to get the curation reward, not because they necessarily like to support the post. Also the curation reward algorithm is so complex, that not many will understand it.
We could give the saved money from the curation reward to fully verified accounts. This would help greatly to encourage newcomers to participate at steemit. More on how this could look like please see my other comment below.
Up Vote for the curation rewards lol but good point, being able to vote on the allocation of generated funds is definitely also an incentive in itself.
" reward to fully verified accounts"
We need to be making crypto-currency (and anything dealing with it, such as this platform) more private/anonymous, not less.
verifying accounts does not mean, that all accounts need to be verified. it just means, that you get an universal income if you have a verified account. nothing should stop you to create 100+ unverified accounts.
