For whatever reason, my blog is attracting a fair amount of spam in the form of bogus comments aimed at embedding web site addresses on my site.  I'm not sure why.  I'm deleting about a half-dozen of these each day - a noticeable increase from the few a week I've averaged over the past couple of years.  I wish I understood what the trigger was for them...I love comments, but it's annoying to get my hopes up only to find out that it's spam!
