Tag sets have introduced a way in which identical tag names are associated across SOFU & SX sites. We've got a few inconsistencies with SO, e.g., while excel and excel, are the user and programmer questions associated with the well-known piece of software and match, microsoft-word and msword don't.
There's at least some value to having the same tags used across sites, since it makes it easier to track related questions across sites using tag sets. Is it worth trying to do this? If so, how should we go about it?
