Tbh., I wouldn't say that none of these communities are decentralized completely, but it's a work in progress for some, that's for sure...
I would say that the problem is very often the fatigue (and probably focus) of the leaders... After some time, it looks like the community isn't moving in any direction, and without empowering your members, it stays there or going down...
It's a great thing to praise the community and supporting by speaking about it, but when the support in the field is missing, it's like shooting in the air... Maybe I sound a bit pessimist, but I like to bring my concerns to others...
A lot of people are searching for ONE leader that will save them all (how suitable to this situation with elections in the US... lol...), and when they aren't saved (as it's impossible), they quit...
That small gap when they are still motivated, we have to show them the way of empowering themselves... If we succeed, they will maybe change their mindset and save themselves... :)
Thanks for your opinion! Appreciate it very much!
