A video of your dog being "cute" with no explanation
One of my pet peeves as well. I do respect that not everyone are authors, and I have full respect for people that want to use Steem for distributing and getting rewarded for non-textual content, but please give a short description of the content.
I'm seldom having any privacy, always surrounded by family, colleagues in the office or strangers on the metro. It's also not always a given that I have enough battery power or network bandwidth to watch videos. Some people are even blind. Don't just post a video reference, write some few lines of context to explain the video. Same goes with photos.
Absolutely, I am glad you agree. I honestly would not feel right if I posted a photo or video and nothing else, but some people have such good videos and photos I guess they feel its not necessary to have an intro, but that sometimes leads to confusion.
At least with videos, I need to know why I should bother to play the video, or I will simply not see it.
Sometimes the title alone can make it so you understand completely, but its usually a little harder for someone that is new to watching your videos. It just helps draw people into your video if you also provide a short description... a long one is not required since you already have the video.
