Russell A. Beattie, a self-proclaimed mobile industry strategist and evangelist who has been diligently maintaining a blog about the industry for four years and 3,000 posts, has cut the cord.

On Saturday, Beattie posted his final comment and started asking his blog-readers worldwide to unsubscribe to his RSS feed.

He wrote: "There's lots of reasons, but generally this is a continuation of the full-reset I started back in January. At first I was actually thinking about just transitioning to a more of a weekly blog where I write less frequently and was sort of cleaning everything up with that in mind. But then I just decided that I really needed a break, and that I'd really much rather start from scratch at another URL some other time when I'm ready to write again. Lot less pressure that way to do something new later on, and a lot easier to get out of the habit of posting daily now."

Beattie continues in his day job at Yahoo!, where he is helping with the company's mobile products and services strategy.
