I agree with a lot of what you say but disagree that following a 15 week plan for a 10k is boring and unnecesary. I am currently following a 11 week plan for a 10k. I am NOT doing it so I can run 10k (I could nip out now and run it) its just I want to have the right pacing and miles in the tank when I hit the start line. Its just a personal preference.
As mentioned above I am also following a 10k training plan to get ready for a couple of spring races. I think there is nothing wrong with what you are doing I would just suggest that based on your running history your plan is starting at a pretty basic level.
I hate to be negative and I am not one of those who automatically knock bloggers. Surely the whole point of a (good) blog is to tell a story and share a journey. An experienced half marathoner knocking out a 10k is not that interesting.
There is a good discussion around following a plan versus not, just not in a blog style.
