I've never understood it either. It's either losers in general, or the sock puppet accounts of some of the other already known losers that don't want to show exactly how low they really are. If people want to take the time to write a story, or film a clip, power to them. If they are proud of it, that's all that matters.
Sadly, you're right. I'm no master scribe, but I've come to realize that the intelligent folks around here will appreciate the hard work that went into creating a story. It's the self-loathing types that will chime in with such helpful comments as "lol thiss storry wulda bin beter wit mor feetz." I say fuck 'em. I've seen samples of your work before and I think you're very good at it. I have no doubt that others will share my opinion. Don't let the trolls get you down.
