It's all about nostalgia. While it feels, at times, great reminiscing about times gone by...you've really enjoyed, and you're under the impression there's no comparing ever... it's best letting it go for the most.
The scenery changes, new people pop up. New ideas, new thoughts, new trolls etc. people with different views and passions. Sure, this isn't the old buf anymore. And it's stopped being this a long time ago. But nevertheless, I don't think of the current buf as any lesser. It's just different.
