The Netflix Techblog has released a graph of performance by Internet Service Provider - which I modified to demonstrate the Looming cable monopoly as identified by Susan Crawford (and recently discussed here by Mitch Shapiro).
The trend is unmistakable. There are 2 distinct groupings - the cable providers all beat the DSL providers (Verizon is in the middle, likely due to its fast FiOS speeds averaging with much slower DSL connections). At the very bottom is Clear's 4G WiMax - you know, the superfast wireless that is the key to fast broadband!
Communities need to read this chart and take a lesson: the future of broadband is not pretty if you do not have a network that puts your needs first. Cable broadband speeds are increasingly more rapidly than DSL, meaning a local monopoly on high speed broadband, with DSL slowly becoming the modern dial-up.
