I love how-to blog entries = its a tutorial, a cheat sheet, a process guide. Especially when, like this one, they give fairly detailed instructions on services, techniques, and sequencing.
I agree, but I think instead of saying "How to do XYZ" it should be "How I did XYZ". Just because it worked for one person doesn't mean it will work for all.
My only problem with a lot of these "How to" blog lists is when they fail to provide context. (not saying this one particularly, just a general observation)
