The featured tag, a special moderator-only tag, had been on several entries (such as the FAQ and a post about how to use LaTeX) and is now gone. It caused those tagged entries to show on the parent site, in the right side bar when viewing a question. With no entries tagged, that side bar panel shows the few most recent questions on meta. Was it removed intentionally? Why?
To prevent long-term staleness, the featured tag will only remain on a meta post for a maximum of 30 days.
You can re-tag the question with featured and it should stay featured for another 30 days.
