Apropos of my post on ungating research, Scott McClurg suggests Academia.edu. Its purpose is:
Academia.edu helps academics answer the question ‘Who’s researching what?’:
– You can find people with similar research interests to you
– You can keep track of the latest developments in your research area – the latest papers, talks, blog posts and status updates
– You can create an easy-to-maintain academic webpage, listing your research interests and any papers you have written.
