err...to provoke interesting conversation?
So imagine one day you go to your profile then you notice that this
guy has been looking you up 30 consecutive times within a month! So
you went to his account and add him, then you notice he has his MSN
add there, so you add him. The next time he comes online, you will
message him to ask out of curiousity,"Hey, why do you look at my
profile so many times ah?"
Might even help some ppl confess their secret crush...
