Too Many Open Source Licenses?

Are there too many Open Source licenses? With many companies starting to release their own OSS licenses, there are now over 50 that are approved by OSI. Eric Raymond said OSI has been aware of the potential problem for a “couple of years,” but things are not that serious right now. It's not a problem because fewer than half a dozen of the licenses are of any real significance for developers. I would tend to agree. I am still looking for ideas and feedback on the problem I ran into recently regarding the CC and GFDL licenses though.
