I totally get this. I think that I'm most silent and my blog is very still when I am doing a lot. It doesn't always mean that I have anything to show for it, but zipping around all the same. :) Thanks for the sweet mention on your site. I like your blog quite a lot!
As an introvert (and a bit of a homebody), I find it more important to be comfy than busy. I am glad I discovered your blog; it is very homey.
