Steemit is a great platform for education, that's true but like any other online based education, any information in here should be verified first. Life lessons and experience might be fine because it is interpreted differently by different people based on experiences and view on life. Hard factual topics on the other hand, should be verified by sources. I saw some of the writer put source's website link or books at the end of each articles. That's a good way to deliver so that it can be verified by reader. Just my opinion. Cheers.
