Massive internet companies buy out their competition as they grow to add service offerings and functions to their products. They subsume and centralize markets and in the process, eliminate small business and pet projects. The start-up mentality is generally to produce a product which can then be sold to a Fortune 500. The logic of the internet of things is that it's best to have as many things operable in the same place or system to iron out inconsistencies; the smart phone replaced dozens of other hardwares like mp3 players, telephones, calculators, timers, notepads, the list goes on.

I think single-use websites are fun and have many other advantages including simplicity, intelligibilty, lack of clutter, and lack of ambition to be all-encompassing. What's listed here is a short list of some of my favorites based on my own interpretation about what single-use means and granted, very subjective and debateable. I tend to give preference to sites that are more like that fill a novel curiosity or need and are run by an individual or small group, or hobbyist community.
