For sure, you can't expect people without any ability (such as me) to do something useful. Can a donkey do what's horse's forte? Unfortunately, most of such work (whether propagation, publication, refutation etc.) needs knowledge. While wealth may be gained fortuitously and instantaneously (by means of miracle, inheritance or act of crookedness), knowledge doesn't come that easily and miraculously. If there's something much simpler (commensurate with my ability and resources) for me to contribute, then I would definitely be remiss in my duty if I don't do my part.
