By chance, while surfing I came across Get Your Plugoo , a site that lets you install a widget to his Wordpress blog for example and get in conversation with curious visitors.

Widget and instant messaging

I have not tested the product, but I saw it worked and it looks quite nice. The tool is based apparently on IM accounts already existing. While useful gadget or widget that is true can not happen. While some have already tested this kind of tool, I'm interested in your opinion ladies and gents.
