A classic information illusion arises on the net: the conflation of a click with a look with a read. It's easy to track how many far away computers access a web page, not so easy to figure out whether anything on that web page was seen, read, thought about, etc.
So, a small experiment so I can come up with a tentative correction factor for the "visitor" count. If you actually read a post here could you post a very short comment to the effect of "yes, in Portland (or where ever)"? I'll set it so it can be anonymous and not require signin and so on. I'll leave this hear for a day or two to see if it garners any results.
Just click on "comments" below and a new window will open up.
