Why do people blog?

Somehow this question just popped out of nowhere in my head...

do ppl blog for attention? (well, not for me, i think, but its starting to be.. i admit)

or do ppl blog for their own self interests? (as in, just plainly an online diary? i dun, i think, not totally)

then why do i blog?

i blog cos i wanna let ppl know how i feel.. cos i nvr showed any of my emotions on my face, i dun talk about my woes alot, it's just an instrument for me to vent my angers, woes, in a way, my blog is my listening post, a friend... though most of the time im talking to myself when i blog...

i blog for tat little attention it gives me, i want my frens to look at my blog at times, want them to give comments as there's alot of things i can't decide on my own, due to my super lack of self-confidence. i want my frens to know wats going on inside me so they wun ask me, and they wun meet with awkward silence or avoidance frm me..

or maybe even sometimes when u are very unhappy with someone, u'll tend to hint here and there on ur blog and hopefully tat person dun get ur hint cos u just want to let it out..without spoiling ur relationship...and maybe enhancing ur relationship if tat person does get wat u mean and try to be a better fren/bf..

i blog for another reason too, to try improve my english, which i dun think had much effects. my english is still bottom scraping poor. pardon my lousy descriptions. or imagery. or watever. do u even call it an imagery? i just cant think of that word! i really do feel i disgrace the entire arts cohort. my english is so darn poor no one ever understands wat im talking abt. no wonder my gp got such fucking lousy grades.
