How quick and easy it is for you to ASSUME the author hasn't done research. Actually, I did extensive research. And that's how I reduced a list of 14 to just 4 that you see now. Even with the once left, I stand to be corrected as research and me briefly testing out these platforms doesn't make me all-knowing. That's why I clearly state that people should do their own further personal research on any platform introduced to them. By the way, thanks for dropping by to comment. Your time is appreciated.
