> In short, Logseq feels too big, feels too hard to start with, and demands too much at the first impression. If failed to get me, and I failed to get it.

This is interesting, because it wasn't my experience at all. I migrated from Roam to Logseq after I realized I didn't use enough of the fancier features to justify the price. Basically I open Logseq, take notes in my daily journal, and tag blocks so that I can easily pull them up by topic/person/etc later. That's all it took for me to get started, and also as far as I've felt the need to go. For better or worse I have no idea what other "kitchen sink" features it has.
