I've added a number of links in my ERMIE over the years, but I have no clue anymore what's mine and what came w/ BW. They had lots of links pre-assigned.
I'm finding, however, that I'm Zotero for all my bibliographic work these days, and that includes links to web sites.
If you don't use Zotero, I can't encourage you enough to check it out. It's free. It's multi-platform. I have come to use this nearly daily as a way to organize books, articles, PDFs, and web pages I come across. It's such an outstanding bibliographic tool. I did buy the Scanner for Zotero app for my Droid X, so I'm prepared for when I go to something like the Society of Biblical Literature meeting and can use it for adding books I see to my lists and making notes on them. Zotero also allows for collaboration with the sharing of libraries, so it's one way I share my bibliographies with my students and allow them to add to it. (There are Zotero mobile apps for other platforms too.)
