Trackback is 1337 and k3wl1ez and all, but these validation issues are a hitch, as is the lack of an anchor in the link-back to monthly archives. Plus, a MT bookmarklet is needed to use Trackbacks with any degree of convenience; otherwise, you need to enter ping URL’s manually. I guess I’ll need to blog from Mozilla from now on. (The JS bookmarklets don’t work from my regular browser, Opera.)
