Greetings:
As many have noted, journal impact factors and various other ranking measures have significant problems. To provide additional information about journals, we have set up an effort to "crowdsource" management journal rankings, at the All Our Ideas (the technology platform was set up by Matt Salganik @ Princeton).
If you have a few minutes, rank the journals (or see the current rankings):
