I noted in both my qualitative study(pdf) of science blogging and my social network analysis study (pdf) that there are more trolls in some areas of science blogs than others, and they’re pretty detectable by looking at the patterns of links.
Anyhoo, seems like although some fields get more trolls than others, each field has a unique set of trolls with different approaches. Now I’m not talking about people who actually have substantive arguments that further the conversation, I’m talking about obnoxious people who hijack the conversation.
Actually, with that said, it would be kind of interesting to have a typology of the various flavors of pseudo science activists and what not who cause hate and discontent in blog comments. You have the anti-feminists, the anti vaxxers, etc.
Not really a troll, but this post about the sorts of e-mail meteorologists get got me started on this. Sigh.
