I was looking at solutions for blogging through my desktop rather than through the web panel. For Mac OS X there are several solutions, but I like ecto the best. It is not expensive ( $17.95 ) and it does the job well, for now. It detects by itself the blogging system you have installed. The only small drawback I noticed is that it uses a few perl modules that are not the easiest thing to install even through CPAN. If you use Wordpress 2.1 you have to fix a bug in xmlrpc.php -> Around Line 980 look for ‘categoryId’ => $catid, and change it to ‘categoryId’ => (string)$catid,. The solution is from the Wordpress forums and the bug is fixed in the latest version.
