I recently tried the new revised version and it didn't like my blog's "flavour" data. I had a look at the code and I didn't like it - well not enough to try and fix it.
I can keep my old Blosxom install which does work perfectly well. I could try something else (e.g. Bryar) - but there are not that many light-weight non database blogs about, or I could write my own.
I'm really tempted to write my own, not as a fork of Blosxom, rather a fresh application that can use the same filesystem data, similar templates and possibly a few extra features. My plan would be to create a OO module with a very simple wrapper app that could be a mod_Perl module or CGI script.
