"Non-posts"

• Recently I've been coming across more and more blog posts that contain only links to other posts (sometimes there's a little added explanation or comment). Sometimes it's about the blogger's earlier posts ("One year ago today on [name of blog]...", etc.) and sometimes it's links to other blogs.
• While it can be useful to see links to other people's posts (and it's definitely one of the ways bloggers keep their networks going), sometimes I think it's a bit of a cop-out to do this too often. As far as the blogger's own posts is concerned, sometimes a link to an earlier post is integrated into the text ("As I mentioned earlier [link], I think..."). That's useful, because you can refer to the earlier information if necessary. But those "One year ago today" links without any further content annoy me sometimes.
• What do you think? Are these "link posts useful?" Do you read them? Do you skip them? I'd love to know. Drop me a line!
