The Reinhart & Rogoff saga continues.
One point that hasn't been addressed: Outside of the issue about the significance of the data errors, the main complaint seems to be that Reinhart & Rogoff didn't do enough to clarify that the correlation between high levels of sovereign debt and low growth was not necessarily causal. Countries often had debt because they had low growth, the high debt isn't necessarily the cause behind low growth.
Critics of Reinhart & Rogoff then go on to point out that this paper was a major driver behind the austerity movement because politicians supporting austerity often cited this study. I'm not sure if people making these claims really think that Paul Ryan would be okay with budget deficit without being able to talk about a 90% level in debt/GDP, but it's funny that they are making the same mistake they accuse Reinhart & Rogoff of making.
