I've learned a great deal from...
@Sunstone (the best threads.
Period. amazing, crazy, wonderful mind and very funny).
@Windwalker (incredible knowledge of mysticism. The best on the forum I think.)
@Terese (the go-to person for Vaishnavism, also really knowledgeable about Hinduism more generally, and also such a sweet, lovely person. She's a delight to chat with)
@metis (incredible commonsense, down-to-earth wisdom. Great guy).
@Buddha Dharma (impeccable knowledge of Buddhism, even though he doesn't seem to realize how knowledgeable he is (which is endearing) and really fun to have a discussion with).
@Orbit (vast knowledge of mysticism, enjoy posts a lot)
@columbus (very well-informed about all matters Catholic)
@Polymath257 (he's a genius. Nuff said. The go-to person on Quantum Mechanics).
@Aupmanyav (my god, he is a scholar of Hinduism, right? Incredible).
@crossfire (really knowledgeable about Buddhism and mysticism more generally. Have immensely enjoyed interfaith discussions with this poster. Crossfire finds great comparisons between Buddhism and Christianity that simply had never occurred to me before).
@von bek (intelligent, especially learned about Buddhism)
@SalixIncendium (another poster with great insight into mysticism and all round good knowledge of a range of things)
@Revoltingest (he's hilarious and easily the wittiest poster on RF, and the go-to person on Libertarianism.)
@Katzpur (the go-to person for anything to do with Mormonism. Also, just a lovely person)
@Carlita (another poster with great knowledge of Catholicism)
@Srivijaya (very knowledgeable about Buddhism and Eastern Christian mysticism. Brilliant for interfaith discussions)
@lewisnotmiller (he's really smart. And writes well-written posts. About practically anything)
@idav (another poster with great knowledge of mysticism)
@4consideration (all round informative posts)
@StarryNightshade (lovely guy and has had an incredible journey through different religious belief systems. I believe he's a Jew now. He is really well informed about comparative religion and Judaism is lucky to have him)
@Shiranui117 (the go-to person for Eastern Orthodoxy)
@Laika (a fellow political leftie, the go-to person for all things Communist)
@Quintessence (the go-to person for all matters pagan, so wise)
@sayak83 (mathematics, physics and Hinduism. Incredibly smart)
@PopeADope (Catholicism and funny)
@Brickjectivity (New Testament scholarship, I love discussing it with this poster)
And a good many others! (I'm adding as I remember the usernames) I keep going back to my list because there are so many brilliant posters on this forum. I know I've missed some great people, which is really annoying...sorry if I missed anybody.
I'm slowly filling in details now too about what I've learned from different posters.
