Well, it’s Facebook actually.
When you upload a jazzy new picture to an album, a specific album, somehow Facebook shows it to others as a new upload to that album(all ok so far), and then when these people ‘Like’ it or comment on it, they are actually, and probably without realising ‘Liking’ or commenting on the album as a whole, not on the specific photo.
So, you have your album, and lots of comments at the bottom of ALL the photos saying things like, ‘Ooh, nice cat lying on a spanner’ or ‘Wow, you’re so radical jumping over that bus on your bicycle’ or something, and they don’t relate to owt specifically.
Meanwhile, you open your picture of your cat lying on a spanner for example and it has no comments…
First world for sure, but annoying. Never used to be like that…
