Is there a "blog culture" ?

A discussion has started on my french blog and I was curious to get your ideas about a question a Le Monde journalist asked me two days ago: "is there a blog culture" ?

Here is a summary of what I answered as well as my french blog readers in comments:
Yes, there is a blog culture defined by:
-the willingness and pleasure to share his thoughts and experiences with others
-the growing importance of getting what others think about an idea or on opinion. As soon as a community exists around a blog, the author tends to ask more and more questions to them.
-bloggers help each other a lot, they are also capable of launching collaborative projects that would be very difficult or impossible to launch alone.
-getting information from a high number of sources every day becomes very important to most bloggers who end up reading tens of blog feeds (if not hundreds in some cases) every day.
-bloggers want to be in control on how they read the news, they don't want it served like a gospel, as most newspapers do
-bloggers tend to be global, read international sources and want to meet other people (one of my french blog reader quotes the "les blogs" event as a proof of that, so many people who travelled so far just to meet the bloggers they have been reading for so long)
-bloggers want to meet in real life, once they formed a community online, they organize dinners, parties, conferences, to meet
-there is a "common code": a vocabulary, a way to write posts, and behavior codes (quoting other sources when you use them, linking into them, etc)
-bloggers get so much used to providing feedback themselves that they are very frustrated when they read, listen or view MSM as they are not able to comment them
-the fact that bloggers invest so much time in their blogs, usually taken away from MSM, leisure time and sleep time, this irresistible will to share with others is a strong common point
-the culture of speed: the need to post or react instantaneously
-a need for recognition, bloggers want express themselves and get credit for it, resulting in many outside observers talking about bloggers as "huge ego-centrists with too much time in their hands"

Do you think the above describe a blog culture or is it just fake ? Do you see any other characteristics of a "blog culture" ?
