Along with article content itself, the comments become inaccessible after a certain, rather short period.
If I have commented or asked a question on one of the articles, I want at least to be able to see if there are comments on my comment or answers to my question. I don't mind so much losing access to the original article.
It is especially frustrating that SA continues to notify me by email that there are new comments on such-and-such an article, when I am unable to read them. It seems rather greedy of SA to set things up this way.
