I tried to do this, but every time I suggested getting rid of the old wiki someone would object and say they checked it three months ago. It was still like this after it had been read-only for years. There's a Japanese site for tech blogging called Qiita that puts a warning at the top of any post that's over a year old. While a scorched earth policy could be more satisfying (and potentially safer), using a warning might make it easier to get buy-in. Here's a random Qiita post with a warning (yellow box): https://qiita.com/k_s/items/c7cee55dba4a74517232 https://qiita.com/k_s/items/c7cee55dba4a74517232
