I figured it would be a good idea to have a place where us testers can come and report to each-other on what sites we find as being consistently broken with the latest Sneaky Peek. This is not to say that this should be a replacement for bug reports, but I know that I would find it helpful to know that others were experiencing the same problems as I am. Maybe we can even come up with some solutions!
Sites I have noticed are broken:
