some are worth more than others. the kinds of contributions that are more meaningful (articles, etc) are worth more.
at 1,000 points i get you a free t-shirt (as long as they are not achieved through spammy methods)
UPDATE => Nov 11 2008 - we do NOT give out free shirts anymore (we did this for a few weeks and stopped in 2007).
that is a pity, really
Do I get to pick which T-Shirt?
