Well, Wirebird is “done” enough to run a live website; it’s more or less to the point of being a drop-in replacement for Plerd and then some. It’s powering DelanoWichita, the neighborhood website I can’t seem to stop being involved with despite being half a continent away now. It’s getting a little fancier than Plerd, in that it accepts input from multiple directories and makes them separate categories and/or authors.
It also produces JSON versions of each page, a la ~anil’s thoughts here. The structure of those is a bit placeholder-y, but the next step is to leave that end of things alone and play around with the current state of JS and build a web client. (The last time I played with JS, jQuery was the current hotness.)
