Eric, didn't want to spam you on twitter. I'm curious to learn about your thoughts on block size, have you written about it anywhere? Was reading this wiki article and it came to mind in regards to how it relates minimum utility threshold for value transfer. Wondering what you think of bigger blocks, when/why the size should be changed, how it relates to the relevant principals described in the Wiki.
