I've got my tongue pierced and a few tattoos and while I'm still completely in love with my tattoos, I really don't care too much for having my tongue pierced. And it stems mostly from the fact that my tattoos have a story behind them and something communicated through them. When people ask why I have my tongue pierced I usually just tell them that "well I was 18 and really wanted it"...
And it's the same for these "bod mods". I can understand scarring if it's done into a particular design but the random scars (like the cheeks of the guy in the first picture), implants, and extremely gauged lips and ears is where I draw the line. They communicate nothing but pretension and a desire to be looked at strangely.
Soon enough, looking like
Ephialtes from 300 will be cool.
