Impact factor making less and less Impact.
Impact factor and citation are becoming more uncorrelated. The authors look at physics, medical science and social science. Seems to be the case across disciplines. With the net, and good search data-bases, there is little reason to use impact factor as part of the heuristic. (I’m poorly socially mored, and never quite grokked the impact factor thing, but just went to psyc-INFO and looked for the topics I was interested in anyway).
I suspect Björn Brembs as the one to give the Hat Tip to. (I need to document my sources better) – but he is on a tear about these issues.
