Danah Boyd is currently compiling a list of social networking research articles and researchers. This is a great resource for those of us looking for numbers and research on web 2.0. Here is her request:
I want to track down everyone who is actively doing research on social network sites. (Clarification: i'm looking for folks that are publishing in peer-reviewed spaces, not just researching for their company or blog.) Nicole Ellison and i are plotting to bring ways to bring everyone together. I'm also looking to create a list of all known publications. I know there's more than what i'm listing so i need your help. Please! (Quote from apophenia)
If you know of any additional research please drop a comment on her blog.
