Maybe the edublogosphere isn't a place at all - we all just assume that our experience is a shared one, when our blend of influences, voices of authority and "must share/see/use" resources are so instant and seemingly powerful. A spat between antagonists in the comments section of a blog post can equal a controversy and because the names are so familiar in our own chosen list in the aggregator, we can assume that everyone understands our point of view.
But participating in the edublogosphere is a very individual activity - one that dispenses with the "we". I cannot be totally sure of what others' words are really saying - after all, one culture's sarcastic wit is another's pointed insult. A master story teller in one person's eyes can be a boring, metaphor mangling waste of time in another's. You get the idea.
Where I focus my attention determines what I hear. There are loosely connected groups that could be overlooked if I chose only to immerse myself in one group. For instance, unlike one "famous" edublogger who was once quoted at the pre-NECC edubloggercon meetup, I am never going to see the bulk of my aggregator in one room. It's spread across the globe, in various sectors and countries and now across various services (blogs, nings, groups and twitter). There are nodes on my network that are unaware of each other's existence but there are some nodes that know each other very well. So, the way I see it, the edublogosphere is lots and lots of small places intersecting and interlocking in various spots as part of one big place.
Let's not forget what a small microsm of blogging education is as well.
