I wasn't able to make it this year, but I'll give some brief thoughts. Having clear spending criteria is a good start. However, if something can be attacked, we should look at the best preventive measures possible. I would look into adding a daily cap, something reasonable, that can be adjusted like the APR by the witnesses. Having a cap, ensures there can't be an attack on the DAO where a bad actor tries to drain the DAO. If we had "x" amount as a max possibility a day, something we can all agree on that is reasonable, meaning if it hit that amount, we wouldn't be in bad shape, it seems like a good goal to strive for. This puts at ease any overspending concerns, and ensures the projects that people want funded the most are funded, while adding health competition. Happy to flesh this idea out more, as I know there are nuances to discuss.
