I never really get the desperation to have a 'celeb' following you. I mean yeah it gives you a brief amount of pride and satisfaction that they know you exist (for about a minute at least). But I wouldn't really want a stranger being inundated with my tweets. Plus if they actually follow people they don't know that easily, chances are they won't see your tweets anyway because their timeline will be absolutely huge.
So I feel like there's little point getting them to follow you.
It gets annoying when you see every tweet they make, even attempts at being profound or intelligent, only for them to usually be followed by "omg babe", "I love you" or the dreaded "please please please follow me, it would make my day *cries*".
I mean why should they follow you when you clearly don't listen to a thing they tweet about as you reply with the same thing every single time?
