What to blog on???

Hi all!
This is my first blog and hope all my homework to pull it off fine will work. I've been reading many blogs recently to get a feel of what to write but everything seems soooo good. What matters is i write what i feel most strongly about, at the moment. So how about "my confusion in choosing a topic" as a topic of the blog. People write about communicaiton, networks, linux, windows, tally, business and accounting works, paintings, movies, music, society, girls, marriage, drugs, sex, sip, voip, and all other sorts of things. Maybe i'll write about communication networks because that is my primary worry at present. I'm new to this subject. After much research, i purchased this book by "Andrew Tanenbaum", but this book assumes that you already know some bit of computer networks before you proceed beyond the 4th chapter. So, i got this book by "Ray Horak" from the library and i won't be wrong if i said that this is the best book i've seen so far. The author takes care to explain each and every technology from its origins and take us on a journey through time, bringing us to the present technology explaining its positives and negatives over the previous technology. I liked "Turbo C" by "Robert Lafore" but that book got too descriptive and there was nothing left for the reader to imagine and innovate. It is important that a fresher be directed to the right book very much like directing him to the right educational institute and course, which is often the case here in India.
