My former blog was http://xrunhprof.free.fr/serendipity/. I wanted to change to no longer maintain it myself and to improve its visibility. I bench-marked Blogger and WordPress hosting. Blogger has a very powerful way to customize look and feel of the blog but it’s a bit hard to use for a non web-developer. Moreover it doesn’t have any import and export features, so I chose WordPress. In WordPress you need to pay to have the CSS customization feature, but I don’t really need it.
WordPress import/export format (WXR) is a bit broken. It claims to be an RSS extension but looking at the import source code, it’s not even parsed as XML:
You will see that the WXR are parsed line by line using the php
Serendipity RSS export is also broken as it only export summary but not full content of posts. Here is how I get round those problems.
