> lack of focus on realistic, achievable goals ("go small, then incrementally bigger")

This is basically the problem with stretch goals in a nutshell. Once you get a lot of money and interest, it's easy to add more and more promises to keep people adding money to the pot.

The problem is that each of these things requires more time and effort (sometimes even exponentially more), so you end up stuck in a quagmire of 'fulfil a huge laundry list of promised features before you run out of money'.

I suspect Patreon has some of this for similar reasons. The more money you make, the higher people's expectations are, and the more insane your own promises will get to try and justify the amount of money you're bringing in.
