@matigo I realize the blogging feature here hasn't been used much, me included. Whether that is because blogging is dead or people just don't have much interest & spare time, I don't know. I'd like to think its latter. As for Blurbs, I thought, it's a community gradually growing; adoption rate seems slow though. Perhaps, it may be due to absence of a dedicated client. Am unable to comment on podcasting though, as that's an area I still haven't explored much.
Personally, for me; my posting here is to keep a kind of a journal of things in my life as much as to interact with nice bunch of people to learn, exchange of ideas & thoughts and to socialize if that make sense.
