Gonna add a reference to Amplenote here. I’ve been testing it in the last few days and it seems like they’re going for the Evernote defectors market while integrating some interesting PKM features.
The reason I looked into it is because I still have a lot of notes in Evernote that I was thinking need a more usable, reliable home as Evernote is turning into Nevernote 
Would love to hear if others have tried Amplenote and what their experiences have been.
Superb video on Amplenote for note taking, Zettelkasten, tasks, time blocking
