Having switched to New Blogger, I can't say I've noticed too much difference. Though I was locked out yesterday evening. And today links to individual posts aren't working.
And as always, trying to get to a place where I can report a problem wore out my patience before I could find that elusive place. So the instructions to report the exact error code were rather pointless.
But I try always to remember that I'm feasting on free ice cream, so I shouldn't complain too much or with too much annoyance over a service that usually works just fine.
But if you are trying to click on links in my site and aren't getting anywhere, that's why.
