I haven't found a platform which caters to this group. I guess the approach would be find communities related to the subject matter, which unfortunately are very distributed and not cataloged anywhere. You mentioned, that you practice intensely for months to develop a skill, talking to experts etc. I have recently started on a similar path to strengthen my fundamental skills in my subject area and, that means, learning solo and working on various domain topics for many years. Do you have any general advice on learning topics intensely for months, just curious about your personal approach to learning solo.
