It's certainly possible, but there's no recipient on the other end of any interactions for it. On some Reddit threads, I can chime in years later and ask how x panned out for someone in terms of advice taken, or if they ever found a solution, or what they are now doing after x solution is no longer viable. Most of the value that I derive from older content is being able to recontextualize it for the present day, especially with extremely niche stuff. However, user hostility from Reddit itself is likely going to lead to an exodus of power users, just like with Twitter post-acquisition. It might not be huge numbers of people quitting, but they're meaningful users, which are a sad loss community-wise. Especially if you assume that way more people just view a platform than actually post things on it, which is apparently vastly skewed in that way for most platforms; "lurkers".
