Do bloggers have a responsibility to archive the content of posts that are linked to, so when the post becomes unreachable the information is still available?
I linked to a forum post that described how to fix a problem where your iTunes library file became locked. I didn't post the actual steps, as I didn't get permission from the author. Then at some point later, the thread was removed from the forums at ipodlounge. For a while it was available in Google Cache, but then it disappeared. Now when people find my post from search engines, they can't find the instructions.
