I am testing an XML-RPC interface to the WayPath engine I use to display thematically relevant links to my posts. So far, it seems to work quite well: the results are as good as ever, but they come back quicker and that’s always good.
I have no idea how many lines of code were required on the server side, but client side, it’s very short. The comments outweigh the code . . . . and there’s none too many of them.
