Why & What this blog is? How do i?

it's been abt a month since i launched the feeling of blogging my worklife, my wireless and network technological interest to share the knowledge and clear my thinkings. since that time, i have been thinking that why i wanna blog and what i wanna blog...at last, what is my audience? As i said before, i want to share my knowledge and knowhow, all in all i want to challenge my thinking....But one particular interesting thing i found in backtracking my feeling of blogging is that i was quit reluctant to blog for the sake of no audiance. but finally grasping a straw of optimistism that my blog might be able to get the audiance in some evolved form.............i am now here to blog....
