If you're reading from free relays, are you getting the benefits of paid ones?
Discussion
well people who cannot post note in paid relays or new friends/critics or new ideas in global or network section (with spam too) will be missed
just sticking will paid relays only can become echo chamber or private club in my opinion so balanced approach based on mood will be choice
also pushing own to free relays makes it more wide spread in eyes of unknown or new followers
