It's really not so bad :P. It's easier for our project size to keep everything in one source, one searchable resource to use. (Though I do like commits via email because it allows users to do code review by simply responding)
That's where patchwork is nice: it collects such responses as well, and collates them all into a great big webpage. http://patchwork.ozlabs.org/ is the largest installation I'm aware of, and gives a fairly good flavour of its capabilities.
