I'm slowly pulling all of the elements back together to fix the blog after yesterday's corruption. Interestingly, some of the widgets that have disappeared are no longer recoverable. Google Friend Connect for example, seems to be lost forever, which sucks.
None of the workarounds I've tried seem to work for it and it should not really be surprising since Google has discontinued support for it and is trying to push everyone to Google+. But the blog only has 2 followers on Google+, so I'm in no hurry to share that. My own Google+ fares much better but I can't seem to link my own Google+ to the blog. So don't expect to see that here any time soon unless I can figure it out.
In any case, regular posting should resume within a day.
