Hi ShannonStallard. The points are a kind of score, most users don't pay too much attention to them, some do. Sometimes it's nice to congratulate a fellow user when they reach a milestone like 10,000 points or a million. Tokinjester is right, after 1000 points you can make meme comments with the popular meme templates. For me the fun really started after 6000 points when I was able to make meme comments with custom templates (any image). There is a meme about how many points you get for this or that here
imgflip.com/i/1e4lo8 and there is a whole bunch of good info for users in ghostofchurch's community based memestream here
imgflip.com/m/community_based hope that helps. Ask a question anytime, usually another user who knows the answer will help you out:)
