I've been intensively following and participating in Nxt at the beginning.
It is now the 3rd most successful crypto in the world and should reach 2nd place soon.

The reason why it is successful is its organisation.
The day the crypto was launched, its creator disappeared and left everything in the hands of the early adopters.
At this time, anyone would say the crypto was doomed but the early adopters seen this as an opportunity and seized it.
It started really simply with discussing on the main thread and making proposals.
As it got bigger, people started to create separate thread with questions and voting.
Then the community organized itself by creating funds and committee.
The idea was that there is no creator, no boss so only the very motivated and very competent people should take decision in particular field.
The community had to elect members of committee based on their reputation and statement.
Funds where used to pay members of different committee and to raise bounty for special missions like finding bug and flaw.
No one would take decision in a field that he is not specialized but everyone had to express his opinion.

Nxt has now a separated forum. Have a look at the committees section, there is 3 kinds of committee :
Marketing-committee
Infrastructure-committee
Technical-development

The strength of this organisation is that anyone can be replaced. Some members of committee have left of died ? Doesn't matter : replace them and keep going on !
This is how you make an unstoppable crypto.

I am not saying that we need this kind of organisation right now but we definitely need to aim for it in a near future.
We should start with talking right here and discuss ideas. When we start to disagree, we should put things on vote on separate threads.
