It is from my experience that I see my usage of Twitter has increased over blogging. It isn't necessarily bad, people get updates either ways. But personally the use of Twitter has reduced me from writing big posts on what I feel about Technology or business or anything for that matter. Do I miss things on what I would like to write? I don't know ;)
Have you guys noticed any change in your blogging behavior?
This rises the interesting question of blogging vs. micro blogging. To some they may be different for some it may be not.
PS. Yep you guessed it, obviously I cannot tweet this and hence had to post it here ;)
