favorite quotes

 favorite quotes  is a feature of some silo profiles (like Facebook), where a user can add quotes that resonates particularly strongly with them or are sufficiently self-describing as to be part of their self-description or bio.

IndieWeb Examples
In rough date order:

Kartik Prabhu

 * https://www.kartikprabhu.com/about "We are not nouns, we are verbs. I am not a thing…I am a person who does things…and I never know what I'm going to do next. I think you can be imprisoned if you think of yourself as a noun. — Stephen Fry"

Tantek

Facebook
Facebook profiles have a "FAVORITE QUOTES" feature as the last item in the "Details About You" tab in your own profile, or "Details About ((given-name))" when viewing someone else's profile, and it can have its own access limits (like friends-only). E.g.
 * https://www.facebook.com/tantek.celik/about?section=bio (shows "Favorite Quotes" to "[Facebook] friends only").
