Earlier this year PLOS one rolled out support for Connotea. Pete Binfield, the managing editor wrote to point out that they have a blog post
describing the features, which include supporting bookmarking of items as well as reporting on whether an article has been bookmarked in Connotea.
Its great to see publishers starting to adopt integration with tools such as Connotea and CiteULike. PLOS has really been at the forefront of introducing new technologies to the sphere of academic publishing. As more and more information on the real time reading habits of academics becomes available we will move more towards a situation in which it will be possible to get an accurate picture of the current state of science.
Of course that’s not to say that the instant view is the one that should be the most important one, given the requirement for science to measure itself against the harshest peer-reviewer, stern reality herself. It still has to be better than the coarse tools that are currently predominantly used to peer into the trends of scientific thought.
