StupidZombie is an OpenSource tool that can be used to ‘ping’ several directories to notify about a blog update, but without the need of running it from a webpage (like Blogger or WordPress). You can run StupidZombie from a cron job or using webstart, the choice is your.

Also, StupidZombie has a simple tag generator from directories that support it, like Veneblogs, To2blos, Technoratti, etc.
