If you’re going self hosted, WordPress is a nightmare to transfer over FTP. I was looking up lightweight blogging php and found Chyrp as the first result. It is much better to try to transfer, and is putting WordPress’s self-hosted setup to shame. Just transfer, chmod, make database, create .htaccess that they tell you to fill with the right content, and input the info. It is very barren, but modules for comments and TinyMCE helped. The default theme is not as good as WordPress’, but change be changed. (unfortunately, most themes can’t work on Windows extraction because of the UNIX-ish folders.)
If you want self-hosted, go with Chyrp. If you can’t, then WordPress.com is for you.
