Just a quick word cloud will all the 312 usernames that have managed to earn at least 150 merits as of today (value chosen arbitrarily to allow for names to be readable). Name size is proportional to the number of earned merits.
Nice figure, DdmrDdmr. I found most usernames are familiar to me. The merit system does work, makes it easier to recognize high quality posters and enhances the number of such posters.
