These are the English Planets currently hosted on this website:
In order to read the blog posts, you have various options:
If your blog is about all sorts of topics, I’d investigate the possibility of tagging, labelling or categorizing your blog posts. See How to label your Blogspot posts, for example. Note that you don’t have to go back through your archive and label all your posts. The Planet software only cares about the last four posts in your feed (and about all your future posts, of course). If you just go back and label the last four posts appropriately, you’re good to go.
An extract of new blog posts is added to the Planet on a regular basis. The pages also have a feed which is basically a merged version of all their member feeds, in case readers aren’t picky and simply want to subscribe to all of them using their feed reader.
