Sounds like these "new update" e-mails, you'll get from Randy Blue, English Lads, Blake Mason, You Love Jack, Buzz West, Perfect Guyz, Mike Hancock, and many more...

With three different texts to choose from, the same text will still be used at many, many blogs. For those who actually care about SEO, they write blogposts themselves.

Good thoughts, but I do not think it's a new thing.
