Redirect pages can have a bad effect, though. Taginfo will show if a wiki page exists for a key or tag. Taginfo can't know why there is a redirect. Is this a case where the redirect directs from a "typo page" to the "real page" or is this a case where, like in the maxspeed case, several pages for totally good tags have been rolled into one. So taginfo shows them all the same and might lead people into thinking the "typo key" is the real one, if they don't click through to the page. The problem behind this is that there is no way to mark the reason why there is a redirect. It could be "old now discontinued name", or "common misspelling", or "this page would be basically a copy of this other one, so look there", or probably some other reasons. Redirects hide this information, that could be written down on the page instead. So I think redirects should be avoided. In particular, misspellings would be better handled by having a slightly fuzzy search (not sure how good MediaWiki is for that).
