Like a dog worrying a bone, I keep tinkering with my posts after I have written them.
Catching typos, thinking of something to add. Pushing a sentence this way or that way, adding a picture I could not find when I wrote it. Having fun remembering. Like stories my posts are not static but fluid and changing.
This tinkering throws my google counter all off. When the visits add up, I know it is really me sticking my head back in - tinkering.
That's OK. It's too much fun to stop it.
And isn't that the appeal of bloggig? What you write is not cast in stone, unless you want it to be. You can keep fiddling with things.
