Not all users are aware of the correct accounts to use as beneficiary to burn or donate the rewards. Also it's not easy for them to use @null or @steem.dao when mixing them with other beneficiaries.

I'm not saying that the first goal is the most challenging, but we need to set the base level to a reasonable amount to start working on a new feature. Setting a base level of 20-30 SBD would not make sense in my opinion. In some country 150 SBD are just 1/2 hours of work for a software developer, setting a lower target will not make much sense in my opinion.
