One free interaction

I do this all the time. I hadn't ever really thought about it.
Thinking about it, I'm pretty sure I only do it on webpages and not in Word docs or PDFs. So I wonder if it's a way of compensating for the lack of visible vertical reference points in web text.
Like, with Word docs and PDFs there is a page divider that any given text is visibly distant from. Maybe the lack of that in long web text is a problem.
The interaction isn't free.
And boy oh boy do we hate using the new york times website.
Also, when I'm bored, I like jiggling the compviz windows. That truly is a killer app.
Clicking through and seeing the context was UI, I then thought 'one free interaction' was perhaps some sort of first-time-confirm of major or dangerous operations, or a way to walk people through key steps once before they're really used.
Turns out it's something else entirely... that's misnamed. I suggest instead 'playful interfaces' or 'fidget-friendly interaction'.
