I've never taken SAFARI 2 out of “beta,” but what I'm working on now is sophisticated enough and different enough that I've decided if I ever release the SAFARI codebase, it will be released as SAFARI 3 (well, probably under a different name since Apple took my name and it makes it confusing saying I'm using Safari to look at SAFARI).
SAFARI 2 was essentially a port of SAFARI 1 to MySQL, with additions to make it a blogging tool. SAFARI 3 moves from there into new territory that I believe is not currently being covered by content management systems. My big initiative is metadata — each post will not belong to just one category, it will belong to tons of categories and an unlimited number of other, user definable classifiers. You can find any post by any of the metadata objects owned by that post.
By necessity, I've now introduced a new feature that I think is also innovative. For lack of something better, I'll call it Word2SAFARI. W2S allows you to upload a Word document and have it output into your new SAFARI post for further editing or posting. I've tested using both wvware and the heir of its technology, AbiWord, as the backend to process the documents. Right now, the W2S codebase runs a server side copy of AbiWord to do the processing, which seems to work beautifully. Bold, italics, highlighting and various other Word formatting bits seem to be preserved. Also, and most importantly for my present purposes, it fully supports Unicode.
If I get time and it proves worthwhile, maybe I'll add more uploading features, such as photo uploading or PDF2SAFARI.
