Laurens, so very true... As if blogs on the internet weren't enough, now we get to see them in books? Sure, there's the occasional time this would make sense, but I can't think of any examples. Many blogs post about recent events, at least the ones I see worth reading (recent events as in posting news, basically), which kinda loses it's value once it's not new.
To me this seems to fall under the category of putting reality TV on DVDs... Quite pointless.
Reminds me... I must get around to writing a rant on 'Web 2.0' sometime... Just because the general concept annoys me. And no, I won't post it on a blog.
