Do you keep a "best of collection" in either physical or digital format for when people ask to see "your best photos"?

Recently somebody I work with found my radio blog which has some photos on a location they were searching for, after some back and forwards discussion they asked if I had a "best of collection", while I am not really that active with photography any more (it is now more a by-product of my radio hobby) it did make me start to think about if this is something other people do? I am sure nobody wants to sit and look at 1000's of photos.
I have recently put my own "best of collection" together online.

Thoughts? If you do this how do you pick what to add to it, do you then take some away or let it grow over time?
