I design systems like these. Timeouts are a property of a session, which is kept on the server. I know that it's pretty slow, and the design has a lot to be desired, but minutes for a page to load? That's nuts. Half of this is WebObjects, but I see jspa in there as well.
I do know that Apple is growing, so maybe this is a way to find people suitable to work there. I don't know, but they need to make this place slick.
Suggestion 1: When you email me a notification with a link in it, have it log me in instead of me reviewing the thread I already know about, and have to click through 3 more clicks, including the original email.
Suggestion 2: Speed. You're probably operating on Red Hat now and not XServes. Make it work.
Suggestion 3: Session timeouts go longer. See thread above. Must test on this browser called Safari. It's made by Apple. Also use this other obscure browser called FireFox. And Chrome. And Exploder.
Suggestion 4: Very bloated. The user experience also holds the amount of information per vertical inch within a browser. This thing looks like a children's blog. I know you like your white space and columns and bubble conversations, but make it reasonable.
