Your foresight is flawed.
If these communities wish to reach a bigger audience, they can take advantage of the user base here on LeoFinance and easily send their members our way as well.
You jointly state that Leo has a large audience but finish with the point that Leo needs more members for said communities.
Then finish with:
Our plan is to build out hundreds of these pages in the future. Imagine if just 3-5 of these pages blow up and get mass adoption..
So in reality you're putting high hopes on growth of Leo by external players thus the earlier claim that Leo would be a big enough audience to entice external players is false.
Plus your expecting that out of those thousands of communities you envision residing on Leo only a few will succeed.
So essentially saying:
Communities will be like throwing mud at the wall in hopes something sticks.
