Please note that the more changes the harder it will be to agree on them. For example I will support removing the discount because the discoint is abuse by spam. But I don't think we should change the blocksize any more. It is limited to max 4MB but its dynamic. I am not against for it to be filled to the brim with monetary transactions. And that gives bigger throughput for monetary use. I think in the future when Bitcoin starts being used more and more that will be very helpful. At the moment blocks being half empty is absolutely fine. The block reward is still enough for miners. In fact is was estimated that the spam they mine brings them only 0.7% of their revenue. Fuck spam.
