The first musician to successfully utilize the Internet, Trent Reznor has had it with social networking sites. From the NIN forum:
I will be tuning out of the social networking sites because at the end of the day it's now doing more harm than good in the bigger picture and the experiment seems to have yielded a result. Idiots rule.
The few people who ruin it for the rest, made it just too much of a burden for him to continue to use Twitter, etc. Trent did point out that he is in love and doesn't mind letting us know.
