To have or not to have (a public blog)...

Blog - I heard that around 3 years back and thought of it as a great concept. But then I took three years to create my first blog. Ofcourse I am not the amongst first to start it and hence have a feeling that now I will be called a copy cat. That troubled me a long time for creating my first blog. Well, but I like the concept and hence finally here I am with my first ever blog and blog posting. Second, I fear if I leave it in between, what if I have created a blog just because so many other have it and I like there blogs and want to create one like them etc etc etc. Well lets see - it is quite possible that after a few postings I will abandon it as usual!
