Regardless to the definition of an edge...
I believe that if someone has an edge, they are less likely to share that edge at a public forum where most people are anonymous versus sharing it with someone they personally know and in private or in an environment that they control.
Seriously, if you meet some beautiful sexy woman and you spend many days in bed with and then one day while you're trading....she sits down next to you wearing one of your shirts and nothing else...she then whispers..."please explain to me what you're doing and share all the details"...
I bet you'll tell all.
Now compare that to going to Elitetrader.com or any other forum or social media (e.g. twitter, stocktwits) that's full of people acting like jerks or trolls...the odds of you publicly sharing your edge to anonymous people you don't know while knowing those jerks/trolls will be able to access the shared info too is extremely low to zero percent unless you specially know you're only sharing some details but not all of it.
Simply, sharing is often decided by the location and the person you're sharing with.
