I like your ideas! Here are the ones that I disagree with though:

• Message consolidation (personally I find it much easier when messages are categorized instead of having to keep up with color codes

• Account switching (like you said, I think this really will encourage alt spam)

• Live posts (especially for a network as small as wasteof.money when posts don’t even happen every minute, I really don’t think it’s worth the server weight or the technical challenge of doing this)
