I think there is a bit of a trend with social websites where initially a large amount of the original active user-base is involved in content creation, but whether through gradual growth or an "eternal September" event (I have seen both first-hand), a large influx of users generally attracts more consumers than producers. Right now I think the Fediverse is still fairly niche despite how long it has been around for, so we have a larger share of creators compared to consumers. I try and participate in making stuff where I can :)

I do the same, works pretty well as long as you aren't editing both files at once. Make sure to enable versioning in-case of an erroneous change or deletion 😊
