It looks as though it has something to do with people revising articles. But I've never seen the same article more than twice, but I imagine that people have revised articles more than twice.\r\n\r\nHere are a couple of examples:\r\n\r\n<img width=\"1128\" alt=\"screenshot 2016-02-24 18 13 12\" src=\"https://cloud.githubusercontent.com/assets/1735266/13304557/51d623c4-db23-11e5-860e-5a1914571364.png\">\r\n\r\nhttp://effective-altruism.com/ea/tj/allkind/\r\nhttp://effective-altruism.com/ea/tg/allkind/\r\n\r\n<img width=\"1141\" alt=\"screenshot 2016-02-24 18 13 06\" src=\"https://cloud.githubusercontent.com/assets/1735266/13304579/7d4269f0-db23-11e5-900d-a3acd4a91154.png\">\r\n\r\nhttp://effective-altruism.com/ea/tn/should_we_work_on_taxation_of_the_very_rich/\r\nhttp://effective-altruism.com/ea/tn/should_effective_altruists_work_on_taxation_of/\r\n\r\nIt looks as though the \"Allkind\" article may have a separate issue from that of the taxation article. Both taxation URLs seem to point to the same article (the \"/ea/tn/\" bits of the URLs are identical). But the \"Allkind\" URLs have different bits (\"tj\" vs. \"tg\"), and the number of upvotes is different.\r\n\r\nMost users probably don't notice or aren't bothered by this problem. Having duplicate URLs would hurt the search-engine rankings of the duplicate articles (and possibly the ranking of the site as a whole). I don't know much about SEO, but my guess is that the effect is small.\r\n\r\nThe lack of a canonical URL for an article might be indicative of other problems, so I think this is worth investigating."},"comment":{"url":"https://api.github.com/repos/tog22/eaforum/issues/comments/224412721","html_url":"https://github.com/tog22/eaforum/issues/54#issuecomment-224412721","issue_url":"https://api.github.com/repos/tog22/eaforum/issues/54","id":224412721,"user":{"login":"patbl","id":1735266,"avatar_url":"https://avatars.githubusercontent.com/u/1735266?v=3","gravatar_id":"","url":"https://api.github.com/users/patbl","html_url":"https://github.com/patbl","followers_url":"https://api.github.com/users/patbl/followers","following_url":"https://api.github.com/users/patbl/following{/other_user}","gists_url":"https://api.github.com/users/patbl/gists{/gist_id}","starred_url":"https://api.github.com/users/patbl/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/patbl/subscriptions","organizations_url":"https://api.github.com/users/patbl/orgs","repos_url":"https://api.github.com/users/patbl/repos","events_url":"https://api.github.com/users/patbl/events{/privacy}","received_events_url":"https://api.github.com/users/patbl/received_events","type":"User","site_admin":false},"created_at":"2016-06-07T21:00:12Z","updated_at":"2016-06-07T21:00:12Z","body":"The change I made should prevent a new URL from being created when an article title is updated.
