I know I am a bit late in starting but atleast I am starting..you should consider the fact that 99% of India's people still don't write a word on the blogs (that's 1.2 billion)...so I am pretty much in time :-) .....let's say maybe 10 yrs or 20 yrs ahead of them (i.e. If blogging actually counts as a reliable indicator towards that)
Something has led me to blogging suddenly, some good blogs that I had read recently. Though this is even better if you are looking forward to just pass your free time. And then don't forget that blogs have more effect then you bargained for.
Let me know if you think I should go ahead with writing on some theme.
