one thing that's got me thinking is how most of the blogging tools and news aggregators out there are reinventing the wheel (or at least reimplementing it). when you look at what we have available on every Mac OS X installation (a real web server, choice of popular, interoperable scripting frameworks, support for XML-RPC and SOAP) it's interesting that you've got three of the "Big Four Building Blocks of Blogging" built right in. the fourth building block -- content management -- is a tricky one since nothing built-into the OS fits the bill (Cocoon might be a way to go). but in the spirit of "Navajo blogging tools" (ie, using all parts of the OS), i can't help wanting to use the blocks that i've already got to do the job.
