I'd like to introduce 2 websites which supply good service for more functions in your site.
The toolbar above is made by AddThis. We all know that the AddThis has great share service and this sharebar just makes you feel more convenience to install the share buttons. You don't need to be confused by copying the complicated code to your site. All you need to do is just to copy this simple code below to anywhere in your site:
There is a more brilliant function:
Services that your users use in the Sharebar or AddThis products will show up first.
Wibiya provides a social bar that enables blogs and websites to integrate the most exciting services and web apps onto your site. It is a one-stop shop for fully customizable, easily manageable third party web apps. Wibiya also provides real time stats and information on the apps from the Wibiya user dashboard. (From About Wibiya)
Wibiya requires you to register first and then offer the code for your site. None does AddThis. However, wibiya provides more functions than AddThis those are just said above.
Feel free to try the both and choose the better one for your site.
