I tend to agree..it's a style thing. It has been when the lead author has written for other sites as well. I think it is subtly different from blog spam in that those pargraphs provide a ton of valuable information, but in an attempt to be detailed and precise can become redundant and a bit of a slog.

It seems to assume every article reader starts from absolutely zero knowledge.
