Top Best Torrent Sites.

This is an original list all composed by me, If you liked it , follow me @arnoldwish.

This is an excellent resource! As an educator I'm particularly grateful for the Education list, which led me to quite a few places I hadn't seen before. (Though I doubt that any single person could use all of them "on a daily basis", as you say :p)

Eventually, if we want to make full use of the Internet's potential to change education, we will have to come up with a curated, searchable database of online resources, sorted by topic, level, duration, free/commercial, self-study/teaching materials, etc etc. I've seen plenty of attempts in that direction -- futurelearn is one of the better ones, iSeek (http://education.iseek.com/iseek/home.page) is more focused on teaching materials -- but so far nothing seems to have achieved the sort of fixation and widespread use that would be needed for true disruption.
