Notion.so

Disclaimers:
 I have nothing to do with them.
 I have only just found them
 I have no idea what their roadmap looks like.
 I have just signed on and haven't started using it heavily

 

 I just stumbled on Notion (http://notion.so)
 

 It looks like a modern, cloud based version of Eccopro. 

 

 It looks like it's got a lot of the same functionality
 

 It's available on every platform I can think of...
 

 Has anyone actually tried it for any length of time?
