I'm with Bob. 10+ years. Same topics. Same ideas. Same arguments. It's rare for piano learning (and teaching) to advance in any meaningful ways where learners actually move forward instead of stagnate. There are many stagnaters here so this forum functions more for moral/social support than actual performance/learning support. Stagnation is a habit, not a mode of progress. The only thing that can break this habit is actually learning something new that revitalizes the mind and the body.
Over these past 10 years, I became a musician. Playing the piano does not a musician make. This difference only musicians understand.
This forum, on the other hand, hasn't changed much. It looks nearly identical 10 years ago as it does today. There are a few bells and whistles and the name change from Piano Forum to Piano Street, but other than that, nothing.
