That is true and I would agree with that.
Unfortunately, which sports or what team has enough people that are also knowledgeable about crypto. There is still that barrier out there no matter what we try. The Facebook thing will start to get people educating themselves about it.
What is sorely needed is a better way to search and create sub-communities within the broader area. So far, we do not have this. If the site could be divided into the sports with more than just a tag, that could also serve the same purpose you propose.
