A big ooops…
It seems that there was some sort of cache file corruption on AppliedKarate.com that was showing visitors to the site that the most recent post was in mid-May 2013. In fact, there had been a number of posts since then that do not seem to have shown on the site.
If, however, you were logged in you would have seen these updates. Similarly, if you received the web feed (RSS) you would have received the updates.
I am of course embarrassed that this happened, and hopefully visitors will now enjoy the several articles showing below that had been published since that time frame.
