Hi @samupaha thanks for this most useful article. I didn't know anything about Hardfork 20. I've only been on steemit a week but I have already identified most of the issues you mention with scaling - particularly around the 'noise' issue.
How do you find useful content. Definitely need to deal with language filtering. Communities would be most useful, and feed customisation. There is some great content on steemit but it is hellishly hard to find it!
Thanks for the headsup on the new proposed HF20 developments.
