The journey should be the only reward

My sister, who discovered water painting late in life, is part of a group of artists who share the same passion for art and painting in general. She is really good. She has taken many art courses since COVID. Now, she’s part of a Facebook Group, and when she mentioned it, I suggested creating a website for her to showcase her work, separate from platforms like Meta. She inquired about discoverability. What can I say to her? Is discoverability always tied to rewards? Are likes part of a validation process? Can we be on the web without seeking discoverability or rewards (likes, reblogs, etc.)?
