I've seen so many people here with level 10. One day we'll all get at this level. Do you think GAG needs new user levels? How would you like it to be named? Just continue to counting, i.e. level 11, 12, 13, ... or something that has meaning?
Maybe instead you should be able to apply for certain rewards for getting past 10 and to a certain xper (like 15,000). Like for instance, some moderating skills or being able to feature your question for less points. I'm not saying it has to be this way, just giving examples.
I like the experience level, but something needs to change in some way. At least get rid of the "Guru" title. Some "gurus" I see post the stupidest or more stereotypical things (and yes, I believe they're not being facetious).
Maybe give titles based on accomplishments (X posts, X uprates rec'd, Xuprates given, X downrates rec'd, X downrates given, X BA's, etc)? Dunno, really.
I think GaG needs new users. More people that aren't uptight about everything and more people who can take jokes and find humor in things. People here take this site way too seriously and it almost makes it not even worth coming on. The amount of immature little child-cults there are here are overrunning the place. I think instead of new user levels that there should be a "Kids Section" and an "Adults Section".
