I don't have a proposal to make it better or get rid of it, but it rubs me the wrong way. My gut reaction is that it's just noise - at best a way to emphasize particular feelings some may have towards poor migration practices.
Is it a reasonable and viable tag? Does it improve our ability to categorize, find, and deal with the questions and discussions we have on meta?
There are only 5 questions tagged as such, but over half happened in the last week, and I'd rather see it dealt with early on in it's life, rather than waiting and causing more of a ruckus than need be.
