Quora is an amazing community of educators. I joined Oct 2019, two years ago. My entries and comments on English and math and a little bit on other subjects have passed the 10,000 mark in terms of views. Hard to believe. Well, learners are allowed to contribute. This learner has blogged entries from Quora experts and used their answers in lesson plans. One contributor to science received 2,429 upvotes on a single post; so, my milestone is not remarkable.
