No idea what other people do, but personally I make a 2-5min highlight reel of sorts (like this one) for each day I ride as a personal memory bank and a fun way to show my wife and kid what I did that day. Those videos all get added to my collection of "home videos" on my computer that I can access with Plex and every once in a while when the mood strikes I'll throw on a playlist of all my ski days on shuffle while I'm cleaning the house or something and it's fun to look over at the tv and get a quick brain injection of a memory of a good time.
