Bolding text on blogs

I'm noticing what seems to be a growing trend: Bloggers bolding text that they think is the most pertinent to their post. This GOP Bloggers post is one example. I can't say that I like the practice all that much. In casual reading, a person's mind tends to gloss over the text that isn't bolded, which then strips some of the context away from the bolded text. I think bolding text is appropriate when done in very limited amounts, but blog posts are so short as it is that you really shouldn't need to highlight very much text.
