Hab.la is a powerful tool that lets you chat with visitors to your website through standard Jabber / XMPP clients such as iChat and Adium.
Hab.la lets visitors to your website chat with you without any extra chat software. Their messages show up in your favorite instant messaging app. Hab.la is easy for webmasters to set up and friendly to your visitors' web browsers.
Better yet, Hab.la is free.
When a visitor comes to your web page, the Hab.la chat box is minimized in the lower right corner of the browser. If you're signed in to your IM client, the box will read "click to chat." (If you're not signed in, the box will read "not available.")
When the visitors click the Hab.la title bar, the little chat box opens. All they have to do is type and press enter.
Requirements:
· Adium 1.2+ or iChat 3+
