For reasons that escape me, I standardized on Gmail for my work-related email. The only reason I can think of is the clever way that they thread messages (how, when a new message for a thread arrives, it elevates the entire thread on my queue... I find this really makes following threads much easier than the traditional ways in which threads are handled, although many of my friends disagree). Anyway, it doesn't matter, when I started my job at the Linux Foundation I standardized my work email on Gmail.

Well, I was actually pretty happy with Gmail for a long time. At least, until the new version came out around a month ago. Now, using Gmail is like masturbating with a porcupine-quill glove... except without the fun.
