The problem that I have is that three years down the track I will suddenly think of a topic and remember just a few details of a really good blog post or comment thread that I would like to read again, but I can never find it. I'm just not very good at knowing in advance which is the 0.001% of posts I will want to read again. Storage is so cheap that in my ideal world, I would like to store everything I read and post. But that's difficult as you mentioned.
