Google Reader ignored an important part of the RSS 2.0 spec, but I kept producing content that they couldn't parse, and if people used the tools that existed before GR, they didn't notice any difference, even though GR came to dominate RSS aggregators.
BTW, that's probably a reason why Twitter never could really support RSS, not because the spec didn't cover what they were doing, rather Google didn't.
