The only real 'free karma fest' risk here would be if the OP karma-spiralled. In fact, given the *10 multiplier the OP has gained more karma so far than all of the introductions combined!
Given the 10x multiplier the OP doesn't need more karma, but I would like to see this promoted, since it would probably reach more lurkers that way.
Yeah, I didn't expect this to get me as much karma as it did, but I underestimated the lurkers that would vote me up! I would also like to see this promoted, but I don't care about the karma points.
Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.
Please post a comment in this thread saying "Hi." You can say more if you want, but just posting "Hi" is good for a guaranteed free point of karma.
