I think that people are like: wauw! a tag means you are cool or have some sort of (hidden) power!
And people like power I guess, us humans are all power addicts.
So some people set it as an achievement to get a tag which makes them feel good about themselves and make other people go: wauw! he's got a tag! :O
anyway.
Its just bullcrap, ppl always wanna be in the spotlight xD
I just bring my message and I hope ppl enjoy it :P
I'm like.. jesus! =D
