There are many links posted in answers, and some in questions, that are either stale or broken.
An example is the change to Ant on-line documentation this year to do away with separate 'Optional' and 'Core' tasks areas in the documentation - the old links 404 now. I've fixed a bunch of 'optionaltasks' broken links, but searching for 'coretasks' in Stack Overflow questions returns over 300 matches...
Are there any tools for us to review and fix these - with an emphasis on the fixing - without sifting through completely manually?
Is it time for some refactoring tools for Stack Overflow content, in particular, for links?
Also, I'd be interested to know if there is an analysis of links (as found in the Stack Overflow data dumps) out there.
Answer: there is a rough analysis here of a sample of links and images, but it's getting a bit out-of-date.
