actually not really tell themself to the world, blog is not really only ur personal diary, but also a place where u share some stuffs to the world, also can meet new friends and broaden ur knowledege well..don't talk about those typical naive immature bloggers lah.

and nope, is not a waste of time actually, i wrote several tutorials in my blog and i believe it does provide some help to some ppl out there i believe u sure gain a number of knowledge from one or 2 blogs out on the net right?
