I like your point about designers breaking semantics. Broadly speaking, before a user decides to create a wiki or doc, they have to also decide if the content will be in a structured or unstructured format. Too often I’ve seen people create a bunch of meeting minutes, sales call notes, etc. and realize afterwards that they really wanted a table of all this data so that they can quickly retrieve and analyze their notes. Creating that structure after you’ve created your unstructured notes can be cumbersome.
I also wrote a less in-depth post about various productivity and workflow apps earlier this year: https://www.thekeycuts.com/productivity-apps-to-help-your-team/
