One link that you will find on the code for this ring (that you usually won't find on the code for other rings) is of particular importance - the link marked "Rings." See how I set that in bold and colored it, so that you couldn't miss it?
On any member site on this ring, you can use that link to take you back to the code for one of the rings to which this ring belongs, ensuring that something like total webring navigability can be seen to exist, when we think of all of the sites on the ring as a sort of collective site. If rings are going to be members of other rings, as many have for quite some time, I think that this is the standard that really does need to apply.
Yes, the homepage for this ring is a blog. This is a practical choice, because the major blogging hosts (like Blogger) tend to be far more reliable than the free homepage hosting services, and because of the sequential nature of what happens when a ring is run - first one considers one candidate site, and then another and another after that. For each of the candidate sites waiting to join the ring, there will be at least one post, to which you might be invited to post comments, if you have a site on the ring, because I'd like the people with sites already on the ring to be reasonably happy with the way in which it is developing. You'll be able to follow this blog (and thus, this ring) through Feedburner (see navigational links in the right hand sidebar), being told when there are new sites on the ring to visit.
As I develop a relationship of trust with some of you, I hope to invite some of you to join this blog as authors. One of the benefits to you, should you accept, is that as long as you don't abuse the privilege, you'll be welcome to post about updates to your sites, telling those following the ring about new material.
