I have a handful of albums for my favorite concert photos, stuff to keep track of (DL, license tag, etc), some family, and a couple special occasions from years ago. I’ve completely given up on management now. It’s just a bucket and more new photos are going in probably never to be viewed again in most cases.

I periodically sort them into different albums. Usually from my Mac where I have an "Uncategorized" smart album which shows everything that's not already in an album (plus a couple other criteria).
