I've mentioned before the irony of Atom being touted as better because it is "clearly specified", while at the same time certain large organisations are trying to force the widespread adoption of a spec that is still, in fact, being vehemently argued over, and is full of "To be decided" sections.
I would, however, like to thank the tireless participants in Atom's standardisation process. Whilst testing mail archiving, my 30Mb atom-syntax folder, with its sprawling, multi-forked threads, made great test data.
