I've looked at (and discarded) Workflowy before. I hadn't heard of Logseq before, so thank you for that.

However, I am looking at it now, and while it's a nice little app, it's not an outliner and I am not sure if I am going to be able to find any use for it.

Outliners are explained here: http://outliners.scripting.com/

Why are you comparing Logseq to one?
