I would like to see an option available to the OP where they can return to their question once their issue has been addressed/resolved/concluded to say what happened.
For "how should I..." questions, it would be so nice to read the original question, the answers and comments and then have the OP tell what hey finally did and what happened would be very useful - it would give some context to how the answers helped or hindered their particular situation
The section should NOT be about expanding the original question or asking another question/starting the discussion cycle again. It should be simply a decsription o what action they took (and why) and what it resulted in
Example question - How should I tell a coworker that his headphones are too loud?
Example "follow up" - "We took the entire team to the cafe area of our building for a coffee to discuss several work matters. One item on the agenda was office environment and I was nominated to bring the matter up in a very general/non individual way. Everyone agreed without feeling singled out and since that day last week, my co-worker has noticeably lowered the volume on their headphones"
