No way, I'm not annoyed at all! I tend to forget about @checky when I'm writing the post, so it's always a bit of a pleasant surprise when I receive some checky-ness. And, as you mention, I'm totally having fun with it, so no complaints from my side!
I'm glad you enjoyed the post and a sincere thanks for the effort you put into it...it works great and is helpful, what else can you ask for? Keep up the good work!
