Two articles recently came to my attention because I'm quoted in them. Ordinarily I wouldn't blog something for that reason alone, but each of these articles took a somewhat novel angle on the topic of security fears among site visitors and what businesses can do to alleviate them. Therefore I thought they were worth bringing to your attention.
