BlogBridge update
If you download the latest weekly release of BlogBridge, you’ll be able to tag feeds and individual entries. You can also publish your tags to your del.icio.us account. Apparently BlogBridge will be rolling out its own tagging service in the future, which will help those who don’t have or desire a del.icio.us account. You can read the announcement on their site.
On my Ubuntu linux box I could not get Firefox to start BlogBridge. If you have a problem with this, you have to open it with the javaws file. Mine was located in /usr/java/java-1.5.x/bin/, but yours might be in a different place. If you use Ubuntu and install with apt-get or synaptic, I believe java ends up in /usr/lib/j2re-1.5/.
I ended up launching it by passing the BlogBridge URL to javaws from the command line. It should work from Firefox, too.
