I think the angel/early stage venture industry itself could be added to this list.

Definitely agree with the overall sentiment. Venture is changing more rapidly than ever. I touched on this a bit in the point about blockchain ICOs, but there are other trends at work too.

The QSBS exclusion alone is a total game changer that few know about. 100% tax-free up to $10M in gains for most startup investments should spur a big change in angel investing.
