Test #19 was the winner !
I use a blogging client called Windows Live Writer. It is an XMLRPC client that supports the MetaWeblog API. One thing that has bothered me has been it’s interface for “categories”. From looking at the API, I think it is less of an artifact of the client and more of a limitation in the API. basically, neither were meant for “on the fly” generation of categories.
The problem for me is that I am using “categories” more like keywords. this is how my Tag Cloud is generated.
Well, long story short, I have written the necessary PHP code to extract a list of keywords from the body of a post and convert them to category entries. It matches up existing category values and creates any missing ones.
