I also have to thank Ron Bell for noticing the new XML items over at Yahoo. You can subscribe to a XML enabled site and have it show up in your my.yahoo.com page. Plus sites with XML will show up as having it in the search, although mine doesn’t show like that now. Yahoo has a lot of cool RSS/XML stuff going on that you should check out.
Haloscan now offers trackback along with their commenting system (and it’s FREE!). I’m still not exactly clear on how trackback works but adding some trackbacks to my own site might help me understand better. It’s not the easiest system to use either, but I guess it’s better than nothing.
