They are used for your rank. After you make so many points, you move up to a new rank. Like from baby blurter, novice, and so on all the way up to uber blurter. To see more of these, scroll to the bottom of the page, and click on "how blurtit works" and in there click on "points & levels", it will tell you more about it in there. Hope this helps you out, and happy blurting.
There are used for your Blurting level and rank

Mine are really just something to be proud of for myself to me and have nothing to do with anyone else but I made my ranks, lol. You can always set your own goals beyond that. They move you up in rank which raises your level of responsibility usually and just shows a higher level of experience. Once you are higher up you are also supposed to help out newer members learn how to use the site if they need it and things like that.
Your rank against other Blurters. Like a scorecard.
To measure rank and status.
