Given that 5 of those 8 questions are already closed, and the other 3 have other tags as well as "word", I don't see any harm in pressing forward immediately, without an extended discussion.
As for Q4, I don't have any problem discussing tag deletions. Then again, if we're talking about a tag with fewer than 10 questions, and most of them are closed, I wouldn't have a problem with someone doing some "housekeeping" without a discussion first.
Perhaps it would be better to have one "Delete This Tag?" thread, so that each "lame tag" doesn't get its own thread. Or maybe this thread could be retitled to "Delete 'word' tag? What about others?" and its scope could be expanded accordingly.
By the way, this problem may be more widespread than I initially thought – there are three pages of tags with no questions! And several more tags with just a couple. That said, I don't think sparse use should be the only criteria. For example, I'd probably vote to get rid of the "where" tag, but I might vote to keep "paraprosdokian".

I'd probably be in favor of nixing the last three in that list.
Maybe there needs to be a committee? (I didn't mean to open a can of worms, I just got curious after FF raised the question.)
