in my experienceI plan on using iframes (minimally) to create a place for other bloggers (eg, you) to ping using TrackBack, and this will appear on the home page of the new design. Hopefully it will actually get pinged and not be abused. It's an experiment with a back up plan of using RSS aggregation to fill its place in case of abuse or lack of use. We'll see.
Currently, I have the home page completed and need to do the archive pages, and then port the old content to the new format, then I'll go public. The challenge will be getting the new UI implemented with minimal disruption to my five or six faithful readers. I'll be attempting some .htaccess hacking to limit access during the switch, so please come back soon if the site appears to be down, broken or in flux. Thanks.
