On a whim the other day, I changed my meta name from Lord Torgamus to Popular Demand. I just noticed that the old name has "stuck" to the author tag of a Community Wiki question I asked before the change; everywhere else on meta, my new name displays as expected. Is this a feature? Is it a bug? Mostly I'm just curious, as I can't think of a strong reason in favor of keeping this behavior or a strong reason for changing it.
A question somewhat like this has been raised before, but the previous poster implied that the issue had something to do with migration, which my situation shows is not the case.
