I am not the first one among my friends to write blogs, and for now, I am one of the very few who still continue writing. YC has dropped and shut his blog down, FS's last post was in 2007, and the Soothsayer also seems to be MIA.
However I write blog not because I want to out-last my friends, neither do I want to earn money (i.e. no ads), nor to prove anything to anybody.
I can't explain why I continue either.
