The number of big projects with over a dozen identical comments saying "Same problem" is quite astounding. At what point does the maintainer turn off notifications? 5? 20?
Perhaps the point was that unless you have something useful to add to a GitHub issue then don't comment.
People don't want Reddit style pun threads here and yet to hear complaints about that being enforced, in fact the opposite. GitHub issues is similar in that sense. Everything has its place and time.
Yes, I think that adding the thumbs up feature (which people still use badly) was a good solution to that. It lets you give a "me too" response without cluttering up the comments, and without spamming the maintainers with notifications either - but if they do look they can see people expressing interest.
If the issue is a bug (as opposed to a feat request) maybe it's useful to know how common it is? It would imply its not just a one-off issue with a particular users setup.
