This is an excellent question; I suspect - given the early position in adoption curve--a pretty dynamic list -- I think re-visit and review which of your relays are current active ...via Iris --I believe the 'active' relays are 'lit' ---and yes..there's also 'paid' relays...I too am seeing what can be done without paying though -- I think part of the promise and strength is connecting everyone...even those with only a cell phone kinda thing. -- If you are a content creator looking to monetize -- it makes alot of sense to look at paid relays..imo ...if it's social and tech/engineering...there's several approaches I suppose ... ha! -- GL friend! -- I'd look at your list of relays and maybe mess around with them from time to time...it'll be a different set of options in 3 months etc. --Let's get it fam!
