why bother?

i asked myself a question before i started blogging today... why should i bother bligging if no one will actually read it? so i started thinking about possible reasons like:

-it gets things out of my system
-its like an internet diary
-it gives me something to do
-maybe one other person could read this nd pass it on to make me a blogging sensation

but to be honest, if no one reads it then what is the piont? i feel like an idiot posting bloggs that just sit there collecting vertual cobwebbs and vertual dust. but i think the even sadder thing is that even though i know no one will read this i am still typing. WHATS WRONG WITH ME?
