Overall, the speed is much faster than with commercial Internet, and the bandwidth is symmetrical.
In my opinion, this is a good example of the two faces of the left. One person forms a union and tries to bully their employer into giving them better conditions, or petitions the state to create laws which will benefit them. The other face of the left creates co-ops and gives the corporate world the finger.
I personally believe that the second approach is superior to the first, and rather than trying to twist Comcast's arm into being nice, Americans should focus on building community networks, at least in the cities where such a thing is possible.
