Volokh Buddy Tyler Cowen, citing a long post on Crooked Timber about writing style in the blogosphere:

There is no blogger we would compare with Keats or Montaigne for style. Perhaps style in the blogosphere is a bit like drama on TV. We perceive it only in cumulative fashion. (Few people “get” the very first episode of Seinfeld they see.) Over time we see how the mind of a single blogger evolves, how that mind deals with a variety of issues, and how that mind encounters the blogging of others. It is a kind of drama to see what a good blogger will come up with today. Recall that blogging is a new mixture of writing and editing. So the drama, and the accompanying stylistic interest, becomes most apparent over time. The “unit of style,” so to speak, is larger than the single post. It involves personality, perspective, and intellectual drama as much as it puts forth pleasing combinations of words. And the style spans all the chosen links, not just the written comments of the author.

I’m quite a blog-filter myself. Most of my posts rely on other blogs, and are quite formulaic in structure. This is usually the case unless I go on a full-blown rant, or the rare contemplative essay about whatever comes to mind. Usually my posts go a little something like this: Blogger says “wah,” followed by an inline or block quote, followed by my own take on whatever I have cited.

Putting structure out of the way facilitates wordsmithing; most bloggers who post on a frequent and regular basis usually have posts with an observable structure. I suppose writing so frequently tends to do that to us, but I know this familiarity helps readers as well.
