if:book has an interesting post that draws attention to the phenomenon of individual blogs that come together under a single banner, à la Gawker (one of the first to do so). As if: book points out, bloggers have found ways to form communities and/or affinity groups across blogs for a while now, via blogrolls, discussions across blogs, quoting, etc. This may be something different:
"…what happens when blogs choose to aggregate themselves under a
single masthead? What happens when the voices decide to group together
in a chorus? Do they then become a newspaper? A magazine? A union? A
league? A society? It may not yet have a name, but some blogs have in
fact started banding together to form a new kind of hybrid publication
that is difficult to define."
