A couple of things stand out
- it looms like there’s only weak structure. i.e. we’re not all inbred and only talking to a couple of friends
- what clustering there is is subject-specific. i.e. biologists tend to link to and comment on other biologists.
- the one non-subject specific clustering was of women bloggers. Hopefully someone can tell me whether this is explicit discussions of the problems of being a woman in science, or if hte community is forming itself in a more subtle way.
Anyway, go and have a look and see what you think. After all, you’re probably in there somewhere.
