A MacOS X dashboard widget I hacked together over a month before Apple released MacOS X Tiger. Its design is simple: publish a blog entry as plain-text to a blog such as Blogger or any other blog system that supports the old XML-RPC Blogger API. The original design only spoke the Blogger protocol, but starting with v0.2b was modular enough to generate the posting form programmatically and communicate to pluggable backends. Currently in a state of limbo due to a massive blow to morale after the contest was completed.
DashBlog is probably the most-used software by people around the world, so there's a chance that I'll be picking it back up sometime soon.
Patches are gleefully accepted, btw. =o)
I'm trying to migrate off of the old DashBlog website at http://dashblog.theonelab.com/ to this one so I can better manage the code and the various bits of communication that go out about it.
It's slow going, but should be finished soon. Expect an XML feed for this eventually as well.
