There is a quantitative issue here. The umlaut query had 165 hits. That's a bit too much, assuming they are all legitimate, for hands-on editing unless it's done over a very long term effort. It's also too little for an database wide correction. Maybe if we pool all these accents and quote corrections together we can get enough for a global correction?
At Math.SE we manually retagged all posts tagged (algebra) to either (algebra-precalculus) or (abstract-algebra); since the community consensus was that these two meanings of (algebra) tag should be separated.
It was about 600 or 700 questions and it was done manually.
So 165 questions certainly can be retagged manually, if someone takes that upon themselves to do this in regular intervals. The question is whether it is worth the effort.
While I agree that 165 is not that much, to compare with math.SE does nto fully capture the issue, as the main problem, at least in my mind, is that we "must" avoid too much noise on the frontpage.
Otherwise some complain. THis should be less issue on math.SE as the turnover on the frontpage is so much higher that the relative impact is much lower.
