Edit: Also the link at the top of the page when you click on the "Stanford Persuasive Technology Lab" goes to http://www.captology.org/ which fails instead of http://captology.stanford.edu/ I think they are violating some of their rules with that one.

Update your site's content often (at least show it's been reviewed recently).
But it's ok anyway.
(just curious)
It'd be interesting to see whether any more recent a/b testing gave any indications on whether they still make any difference...
If it is just a blog, then they might prefer the privacy.
Also peculiar, if it hasn't been updated in eight years, why is it using silverlight? [And regarding http://news.ycombinator.com/item?id=1606292 -- that lack of awareness could be considered a bug of silverlight's linux plugin itself.]
