The things that make connections fast or slow are sometimes opaque to users. For the market to really deal with these problems we'd need to give participants better information, either through technical or legislative means.

For example, say I'm paying for a connection with a 20 Mbps upload speed but when I upload to backblaze my upload only runs at 10 Mbps. The problem could be my hard disk, filesystem, CPU, software, wifi, router/modem, ISP, or backblaze themselves.

Currently we don't do a particularly good job of giving nontechnical users the information they need to make rational decisions about what they need to change or upgrade.
