I bugged Stewart about adding this as a code snippet for your own web page -- filterable by type of acquaintance, of course. And to add "title" attributes to either the image or the link, so that we can get mouse hover tool tips with the person's name or nickname.
P.S.: root-relative URLs without the domain name suck. Well, they suck when pasting source code somewhere offsite, anyway.
