Excerpt:

"The most amazing growth story of the first quarter of 2011 is that of Mendeley, jumping half a million articles downloadable for free, from 300,000 to 800,000, growth of 171% in just one quarter!! Since Mendeley is a DIY tool for researchers, this amazing growth illustrates that there is a considerable appetite for self-archiving, once the researcher has a service that appeals to them."
