What always surprises me on the ham world is the huge number of possibilities. Beside having voice QSO in HF or VHF, there are many other options: QRP and SOTA/POTA, digital modes, DYI antennas and radios, SDR, EME, identifying unknown and misterious signal, etc. What I don't like about the communities is that is mostly composed by grey hairs guy that are not really opened to change.
