Links

At its core, the World Wide Web is just hypertext, the HTTP protocol, and a browser program. And the most central of the hypertext markup tags, dating back to the original implementation of the WWW, is the hyperlink. So it seemed appropriate to provide a page devoted entirely to hyperlinks, in order to send its visitors careening out onto offbeat trajectories across cyberspace that they might not have discovered without such a sojourn in Cittagazze (or the , if you prefer that side of the fence).

May you eternally travel a new and unscripted path!
