I’m pretty new to the fediverse, and I find the idea amazing. But one thing concerns me though. How will server owners be able to afford to run servers with massive amounts of data coming through them? Theoretically speaking, if a Reddit migration were to happen how would server upkeep costs look like?
The Mastodon instance sfba.social publishes their financials. They have about 30k total users and costs are about $1,000 USD per month. Donations cover this amount and the extra is saved.
