Someone, correctly pointed out that there are people in the blogosphere that although they do not have their own blog, they are a part of this virtual sphere. They are active members of this system since they read others blogs and/or provide their comments, ideas etc.
This is another sphere then, the outer disk, surounding the blogosphere; encompassing interested readers that may someday become bloggers themselves or not. I guess that this is the case for the vast majority of those who now own their own blog; they started by reading others blogs.
So, which is the reason then that some people tend to stay in the outer sphere and never consider moving to the inner sphere ? Is it more interesting reading at others thoughts, is it time consuming to maintain your own blog, is it something that you always wanted to do but for some reason this never materializes?
Those of you that belong to this sphere, can vote in the corresponding poll.
