Both Google Photos and Flickr got into the "year in review" trend.  I decided to include them both here because they are both photo-related.  Flickr is a bit more basic with some stats, whereas Google creates some nice videos for you.  If you've gone through and have tagged people in your photos, one of  the recap videos it creates is your most photographed people (which is basically members of my household 😹). I did like the Year in Colors idea (first video) as well as the overall photo stats, which include photos with people I don't often take photos with (vis-a-vis my dad who lives abroad).

Flickr does tally the number of photos you've taken, but since I upload everything as private, and then selectively release them into public viewing, I think the viewing stats are really impacted. Not to mention that I don't have that many people that I follow (or that follow me) on Flickr.
