How many people have to use a new topic before it's added to the official pop-up list?
Dead end or joke topics get zapped out of existence by the moderators. But there are a few strange ones surviving yet today because they have at least a few questions attached to them.
“Berkeley” comes to mind as an unusual one. I saw it on a question yesterday. That is what inspired me to ask this. My list of topics includes the gem, “I am not an animal”. Do you have any strange or rare topics in your list of topics you’re interested in? Hover over a topic to see how many questions have been asked about it.
How about topics you’d like to see added? If you have one, ask here and we can ask a few legitimate questions using it to add it to the available selections. The rules are it has to be a legitimate topic and general in nature. For instance, “anthropology” is OK but sub-branches such as “cultural anthropology” would probably get zapped.
