💡 hashtags on nodes

[breck7]

Should all nodes be taggable? Instead of extending the base paragraph/quote nodes, would it better to make node types take an omnifix set of params an use hashtag:

devilsAdvocate
differentPerspective
keyIdea
folkWisdom
tangent
sideBar
hypothesis
assumption
incompleteAdvice
testableAdvice
...

// vs
quote #keyIdea
paragraph #devilsAdvocate
paragraph #differentPerspective
