Kingdon Barrett on 12 Jul 08I was hoping to provide a list of my blog posts from RSS feeds, as well as links to all of the articles that I have commented on with my friends' blogs. I could list all of my friends' blogs and scrape them periodically, but I was hoping for a solution that uses trackbacks, or whatever pingback-style facilities are available on my friends' blogs. Granted this type of support will vary from site to site, but it should be possible to build a complete publishing record automatically, with the standards we have available today. I posted a comment on otierney.net (my friend Tristan is up on all the latest web standards) and I noticed that his blogger is collecting URLs along with emails. I filled in the link to my Radiant CMS on nerdland.org but I'm afraid my blogger is not going to do anything to collect these pingbacks, when they are fired. Can anyone point out an example code segment or project that highlights this type of behavior?
