mood

 mood  is sometimes expressed explicitly in or about a post, by the post author.

Ashton McAllan
has a basic implementation on acegiak.net which can display a mood name and a percentile mood value but currently lacks a smooth ui for entering mood value. She is developing the Moodkind wordpress plugin to add this mood tracking functionality to the Post Kinds Plugin for wordpress. Example post:

Aaron Parecki
At IndieWebCamp Austin 2019, added photo/emoji support to his website to add some mood/sentiment-based analysis to his posts. By adding specific emoji to his post, he can change the image in his h-card to provide a more context-based photo for each post he makes.

"Mood type. 1 = Amazing, 2 = Pumped UP, 3 = Energized, 8= Good, 4 = Meh, 5 = Dragging, 6 = Exhausted, 7 = Totally Done. NOTE: mood number 8 is out of sequence"
 * Facebook - "... feeling ..."
 * LiveJournal - different icons/avatars per post to express mood
 * Jawbone Up - 8 icons from slumped to excited that you drag between to set your mood
 * Exist.io - Tracks mood between 1-5: 1 = Terrible, 2= Bad, 3 = Okay, 4 = Good, 5 = Great

Gyroscope
Gyroscope offers two ways to log moods in their Pro version of their app. Unlike normal mood logging rather than choosing a single mood from a list, they put the emotions on cards and have you swipe right or left if you are feeling it. Then it combines your selected emotions to give you a picture of your overall mood. (need screenshot examples)


 * the first is called Impatient mode. If claims it takes less than 10 seconds and has the following mood options listed to select from with emojis: Happy, Sad, Annoyed, Friendly, Healthy, Miserable, Nervous, Strong, Productive, Afraid, Angry.
