There is a question on Stack Overflow which agglomerate a list of questions related to PHP symbols. This is a good way to discover some rarely symbols, even for someone who has no problem.
Can I add a question on UX in order to gather interesting questions or answers about website forms?
Here are examples of some questions or answers that I found to be inspiring:
- Why might right aligned field labels be better?
- Are users confused by the file upload element?
- Update vs Modify vs Change - Create vs Add - Delete vs Remove
While writing this question, I realize that these questions are not strictly focused on forms, but you can just see these as examples.
One problem will arise: what can be considered a reference answer and not just a useful but subjective answer? Maybe the reference word is too strict. Providing a list of answers without pretending they are reference may still be useful. It may be called Summary of interesting questions and answers about web forms.
