Community, Maintainer, and Usage Page

[nomadscientist]

The community page is awesome
The maintainer page is awesome
The page metrics bit is awesome, and should probs be its own page at some point

Some further ideas

• What metrics can demonstrate sustainability / maintenance? How can we plot that? A sustainability page?
• What metrics can demonstrate developer engagement? Like issues raised as a community? How can we numerically and visually demonstrate community efforts at working together with others?

Issues relating to this which I will eventually summarise
