Interest Check: mastodon.cncf.io?

Given the relatively high level of uncertainty around the short and long term fortunes of Twitter as a platform for communicating with our end-user community, I wanted to broach a public discussion around the CNCF operating a Mastodon instance for project communications, announcements, etc. Pretty much anything you'd use Twitter for today.

My back-of-the-napkin math would suggest that costs would be fairly low (O(tens) USD/mo) for operation in terms of fixed hosting costs. Management and maintenance would take time, obviously, but optimistically O(hours)/mo?
