I tend to book mark a lot of different sites and then return to them much, much later to find them defunct, hideously redesigned or possibly taken over by schizophrenic psychopaths. Having said that here are a few sites that I really like that, at the time of this writing, are still entertaining, informative and coherent... They are presented in no particular order so do not think that links at the top of the list are of greater quality or importance to me.
