I created it to allow myself a different degree of expression from my normal account. Sometimes I just want to release my id - say, for engaging with a not-unsubstantial population on HN of people whose intellect doesn't keep pace with their arrogance. I still try to be constructive and take care of as though it was a primary account. But I really don't care about karma/points. The account is serving precisely the purpose it was created for.
