I can find only 4 working BCN pools and extremepool has 77% of the net hash rate...

The following pools seem to have shut down fairly recently due to lack of support for small pools:

http://bcn.ext-pool.net/

Please support the smaller pools! This severely uneven spread of hash rate amongst all the pools is unhealthy.
