3 social toolbars for extra free promotion

Here are 3 social social toolbars:

Wibiya Bar: http://www.wibiya.com/index.php
Meebo Bar:http://bar.meebo.com/
Gigya Toolbar: http://wiki.gigya.com/030_Gigya_Socialize_API_2.0/Social_Toolbar

I like the Wibiya, it comes with the best options.

Are they automated or do you have to slog through each bookmark site?

It's automated you can add more social site into it. for wp users there is a plugin.
