@evan Somewhat negative. I subscribe to magazines and a newspaper so I don't object in practice to paying for regular content. I have no objection in principle to paying for longer form content such as blog posts, videos and newsletters, but I'm not sure it's worthwhile for the Fediverse to try to develop ways of distributing such items for money; free methods exist, and paid methods have been mostly unsuccessful.
For the Fediverse (or Twitter) as is, I haven't seen any feed I'd pay for.
