I'm not entirely sure if you want a real answer to this or if you just want to make a statement...
The reason there's no JOSS is because JOSS is a week long event, where JOI is just two days.  With JOI  Jon needs to organise hotel rooms for two maybe three nights, build one huge feature, provide one after party and most importantly finance it all.  With JOSS there's a week's worth of hotel rooms, 5 huge features, tons of parties and a lot more financing to do.  Also last time he tried hosting JOSS Simon Dumont decided to throw a fit when he didn't win and messed up the plans for releasing the edits in order.  Last year with just one feature Jon had a drunk naked guy hit his jump and overshoot the landing almost completely, basically what I'm saying is that while Jon is quite obviously super-human not even he has the time to put on a gigantic event like JOSS every year when he's got a pretty busy lifestyle.   Yes, partly thanks to racing, but not completely.  I doubt you even read all of that...
