As someone that has been using reddit for a decade and a half, I agree with you. We the old timers are stuck in the "good ol' days", when reddit didn't have any subreddits, discussions were mostly about technical topics, and the meme du jour was to put dollar signs in Microsoft's name.
I think it has stopped being that a long, long time ago, and Steve kept track better than us what the new demographics of reddit are. I am sad that the reddit I enjoyed is no more, but I am looking forwards to the new crop of discussion platforms (or whatever else) that will crop up.
