If its for free than you are the product or the service might not survive!

I would definitely pay for relays but the value proposition is not clear enough for me as a regular user. Relays are a mess right now. I have no clue which ones to add in order to read relevant content for me and having the best ones to share mine...
From a user perpesctive it would also be nice to have an aggregation service to pay one amount which will be allocated to all relevant relay services...
