This was an interesting explanation on how the markets are wilder than generally assumed. I was aware that a large part of the financial theory is pretty much bogus; this explained one reason why that is the case.

Looking at the mess of Brexit is yet another reason to believe Mandelbrot is very much correct. What bell curve forecast could've predicted something this bizarre? But this cluster of odd happenings that have strong effects on markets is pretty much exactly the behaviour Mandelbrot's fractal theories explain.

I wouldn't have minded more concrete advise – what does all this mean for a small investor? What I got here now is the fact that markets are wild and it's a good idea to expect the unexpected, and that you probably shouldn't trust financial experts relying on the old theories (not that I was particularly keen on that before).
