Question Should sight-reading be emphasized less for piano instruction with new developments in technology appeared to me as similar to another question, so I put a link in the comment. As there was many comments, eventually a mod moved all comments to chat. This is understandable, however the other question is no longer displayed as a linked one. Does it make sense? I didn't want to answer the question, I didn't have much add to other answers, but I think internal linking is something very important for the site in general, so it feels bad they are so volatile.
I don't even know what question to ask. What is the best practice in that case?
Edit: Following @Richard's advice I asked a question on stack wide meta How can I link other questions? but it seems to me that SE doesn't have a solution.
