It's Friday afternoon, so it's as good a time as any for some goofing off. Mary Jo Foley's blog is where I saw the first reference to a Fake Steve Ballmer blog, in the mold of the-now-wildly-popular Fake Steve Jobs blog.

There are 10 posts on FSB now. I'm not going to judge its quality yet (though feel free to chime in with your own comments). I'm not sure it has quite the ear for the executive it's spoofing, as does FSJ. Especially during its early days, FSJ was funny because the language rang true ... sort of. (The language and content in general also regularly ring blue, so sensitive readers be warned.)

Now, FSJ is becoming a must-read full of biting criticism, witty (fake) insights and links to real, relevant articles. It also has its share of juvenile humor, name calling and tomfoolery.

In short, it has defined the fake executive blog category and will be a tough act to follow.

We've wondered around here when someone would launch a Fake SteveB or BillG blog. For the record, it's not us.
