I heard about I-Doser at first because people would talk about it when I was in High School (graduated last year). I thought it was kind of dumb, since some of the people that were talking about it aren't generally very reliable people. I'm 18 now, and not in High School anymore (woo College!). I was watching You Tube videos 2 days ago, and on the 'related videos' an I-Doser Coke video was there. I didn't know what it was, but I clicked it.
The video seemed kind of silly, as a lot of vids on YouTube do (gotta wonder if they're doing what they're doing for the entertainment factor..), but I found the I-Doser forums and, after experimenting a little, I'm hooked on Dosing. Guess those kids in High School weren't talking BS, after all.
