A user from SE Meta recommended that we "feature" posts from our Meta that need more general user visibility and possibly draw more users into Meta.
Some recent examples might be:
For the post in question the featured tag was added Aug 3 and by Sept 9 it was deleted, by Community. This post, When and why is the [featured] tag removed by the Community user?, states that they are removed after 30 (or so) days:
if we did not, every meta would be littered with dozens of forgotten "featured" questions over time.
Also, I can't seem to get it to work, I've just featured the On-topic meta question, but it doesn't seem to show up anywhere in a "Featured" box. Neither on 3D printing meta nor the main 3D printing site.
It seems as if there is a little delay, at most 5-6 hours (I've tested it), between adding the featured flag and it appearing in a box:
It also appears to hang around in the box for another 12- 14 hours after the tag has been removed.
