This is a really useful list! Thanks to the OP.
However, it may need a clear out or update at some point, as a number of the listed sites are no longer working.
For example: 26. sizeasy.com; 39. awesomehighlighter.com; 43. warrick.cs.odu.edu; 54. tempalias.com [at which point I gave up!]
Hope you don't mind my mentioning it.
