Having been both a reader and a contributor on SA, I had a realization. Widely-known investment ideas are not very useful. This is because by the time general public knows about an opportunity, the inefficiency that caused it is usually gone. Fund managers who share their ideas, often do it after a rise in price, as they are trimming or selling their positions. Now, many authors' "best" ideas are often hidden behind a paywall. However, after I read some of their free articles, I have no urge to go behind the said wall. Despite a plethora of well-written investment articles on SA, I rarely find a true investment gem here. My best ideas have mostly been my own. I suspect this is true for many of us.
