It seems like I’m in the minority on not liking popular posts roundups. I do like to link to previous posts when they relate to the topic of the current posts. I’m not opposed to bloggers drawing attention to earlier posts - I just personally don’t like to read blog after blog on Friday and find post after post that are just lists of links to posts I’ve already read - and in most cases that same week or month. I’d rather see a roundup of all the posts on a particular topic - that would give some unity to the post and would include older posts I might have missed. But a roundup of popular posts from the current week or month doesn’t add any value to me as a regular reader. Though it may be helpful for a new reader, it seems that a post highlighting posts on a particular topic over a longer period of time would be even more useful to new readers.
