Great! In Settings > Home Feed of the primal.net web app, I set the following home page search term
"#maths OR #math OR #Mathematics OR #CategoryTheory OR #Logic OR #RDF OR #SemWeb OR #scala OR #Agda...
I also tried the search without the # but that does not give any relevant results.
"Search: maths OR math OR Mathematics OR CategoryTheory OR Logic OR RDF OR SemWeb OR scala OR Agda OR #FP OR SemanticWeb OR topos OR ScalaJS OR Java OR W3C OR WebScience OR hyperApp"
