Is there a way to automaticaly check posts on the main site for broken links?
Do you think it be worth doing?
If we discover a broken link what should we do about it?
I think if you see broken links, you should try to fix them.
However, this is also why we have a policy that posts should always have enough context that they are still complete answers even if the link goes dark -- and that's the really important part.
Provide context for links
A link to a potential solution is always welcome, but please add context around the link so your fellow users will have some idea what it is and why it’s there . Always quote the most relevant part of an important link, in case the target site is unreachable or goes permanently offline.
If an answer is useless with a dead link, it means the answer is incomplete!
