That's how I feel about LEDs :) Can't understand for the life of me what the attraction is :)
World's easiest mod, no skill required to put 'em in, so very appealing for people who want to experiment.
I have a business and personal facebook page, and the personal one is used purely for business as well. It's like the Yellow Pages used to be - you needed an ad for defensive purposes, to keep up with competitors. Now fb is a bit like that for my business. Luckily my partner is a regular fb addict so I let her set it up, and frankly it does work for us. As for finding people, I used it to track down a lawyer who used to work for me, so we keep in touch (I'd like to swing her over to us one day). So yes, it has it's uses for me.
