This blog now has an RSS feed, as per the suggestion of someone on the guestbook. It's still experimental, but works well enough to get the last 10 posts without having to go to the trouble of coming to the site.
I'm trying it out with the actual post in the <description> element instead of a summary, since these posts can't be summarized automatically. So if you use an aggregator you can read the whole post in it. (Depending on your software, the images may be broken as I have been using relative paths for them instead of URLs.) Of course, this makes the XML file somewhat large (~30 Kio currently). If this arrangement if too unwieldy, let me know.
Also, RSS 2.0 insists on an email for the <author> element in order to be valid. Since I haven't implemented per author emails yet, all posts will have my address on them, but with the actual author name listed in parenthesis. Don't worry, I will forward all your philately-related queries to the Philatelist.
Feedback on improvements is welcome.
