Web Site Update Rate

I started adding a Google search bar to more pages on the web site and I noticed that by picking the pages that have not been updated in a while, just happened to be back in 11/11/06. Six months to cycle over pages in the web site. But with 1346 pages on the web site it's understandable. Of course some of these pages just contain pinouts or descriptions of older interface buses ~ facts that don't change. On the reverse, some pages on the site get updated time and again, as I add more data or correct the listings.

Any how, the search bar may help new visitors navigate the site. The attached pic shows how people find interfacebus.com, with 6% coming in as returning visitors. The numbers on the pie chart represent Apr 10 to May 10 2007. For a total of 200,914 visits over the last month.
