Another interesting idea I was talking to thenutz about last night is that instead of having a veriance of chips you could earn in a post, have it to where there is a set amount of chips earned requiring at least 20-30 words per post like this:

20-30 word post=20chips
30-50 word post=30chips

and so on with a max amount earned of 50 chips. This is a great idea in my opinion, and if it is viable, could work great.
