Your blog can be a journey rather than a most-recent-first news site.
You can show your blog content in chronological order, instead of reverse-order default, using a method that relies on external web services to flip the posts around.
These services are web sites that let you manipulate data, in this case having to do with your blog's feed. The services are free and rely on the kindness of strangers.
Web services make my blog-journey hack a little daunting (though people have told me it's easier than it sounds). This approach requires bloggers to think of their content in new ways, and to learn how to use these third-party web services a little bit.
Besides that difficulty, however, there is another pitfall.
