What’s So Great About Adium?

Brian Mann calls Adium “one of the best multi-network [IM] clients ever.” Tim Bray says it has a “wonderful user interface,” while also naming IM generally “an essential business tool.” Eric Meyer, meanwhile, exclaims “Adium is my new chat buddy.”

What’s so great about Adium? Gaim is the engine behind the scenes, but the face of the application is XHTML and CSS. Wit Meyer:

The entirety of an Adium chat window is an XHTML document that’s being dynamically updated via DOM scripting—all of it pumped through WebKit, of course. In creating a message theme, you define what markup will be used, and write CSS to style it. You can even define variants on your theme by writing additional style sheets.

So with all that, how can I not look at it?
