When we first came across the beta of Yahoo! Messenger 3 we were impressed. This feels like an OS X app, not some crappy Windows port! Then we pretty much forgot about the whole thing, but Jeff Smykil at Infinite Loop didn't. He wanted to know why Messenger suddenly didn't suck on the Mac, and he wanted to know who was responsible.
It turns out that Tristan O'Tierney, who used to work on the Colloquy project amongst other things, has had a large part in making Messenger 3 beta what it is. Jeff interviews Tristan about all things Mac at Yahoo!, so go check it out.
