bluebit, the best thing people can do to increase the burn rate is vote in delegates that have set low pay rates. Riverhead's delegate is an excellent example of this at 5% pay rate, I also have an active delegate with a 20% pay rate. Currently the average delegate pay rate percentage is in the mid 80s.
This isn't the only thing to look at though, some delegates with high pay rates have pledged to use the funds earned for various purposes. Many use the funds to donate to charity or other causes that might help people and make BTSX look good at the same time.
I'd highly encourage you and anyone else to stay active in voting as well as going into DAC Delegates section of the forums and voicing your thoughts on what you'd like to see from your delegates. The voting system is great but will only work well if people stay involved, communicate and vote for what they want.
