This feed http://blogs.msdn.com/b/michkap/rss.aspx has stopped working for some reason. The URL still shows what looks like a good feed to the naked eye, but attempting to view it in NewsBlur shows the "Oh no! There was an error!" status. Happens in Firefox and Chrome.
This is an identical error to http://getsatisfaction.com/newsblur/t.... It's a weird Unicode escape issue, and I'm not sure why it's happening. I spend an hour searching every couple days, but I still haven't been able to figure this one out.
OK, all fixed. Please let me know if this fixes the issue for you. The solution was to temporarily switch my JSON encoder on the backup from cjson to simplejson. Unfortuantely, cjson is 10-200x faster than simplejson, but we're talking such tiny millisecond numbers, that it's not worth it.
