Although details aren't clear, especially with words like subpoena being used, this blogger is in a legal tussle over things being said in his comments:
I am sorry I have to be so vague but it appears that I am going to be deposition and logs from my blog will be subpoena for use in a case where 1 person slandered another on my blog. Anyway it looks like 1 of the people is seeking damages for what the other said on my blog. I can not get into any details what so ever about the post or even what state this is in. My attorney probably doesn’t even like me posting this much but I gotta ask does anyone know of any case law on slander in blog comments?

You can't slander on a blog - only libel.
