There used to be a place for site awards (just trophies really) that served just this purpose but they weren't very well publicized and as a result weren't getting a lot of votes and ended up being really prone to abuse by vote-lobbying.
I think the idea was sound but the execution was poor and I wouldn't mind seeing them come back. The trick is that they need a higher profile so that any vote lobbying is drowned out by the volume of legitimate voters. Adding tangible prize is a nice idea was well provided chess.com has the apetite to do so.
As you can see they stopped doing this about six months back:

Someone had placed a post on how to get points here. My first reaction was "Why are you so keen on getting points?". They don't mean anything except to show how many times you've posted. I think the original concept was to show other people here how you've contributed here with help to others. Since alot of posts do help, there are other posts that are simply a forum for insuting others, arguing over little things, and simple ramblings (OMG am I doing it now?).
Anyway..........
I thought it might be a good idea for Erik and the other Gods & Goddesses who run this site, to maybe award a monthy free 30 days platinum membership to the person with the most instructive post each month, thereby encouraging everyone to place more useful posts in the forums. Or maybe have the Erik & the others go over the posts & award points to the useful advice & learning messages, and then when you've accumulated a certain number of these credited points, then maybe set it up where non-paying members like myself (I can't afford it right now, sniffle sniffle) could us them to purchase limited days of god or platinum memberships.
What do you think?
