I don't understand your remark about "Javascript in my blog posts" or how it relates to CORS.
In theory, it should be trivial to make simple, truly "serverless", web-based feed readers like AirSS[1][2]. In practice, many people are prevented from doing this, because the feeds they're interested in are hosted on servers that don't support CORS, which leads to really annoying workarounds (like needing to use a proxy or a separate browser extension, etc.)
Makes sense. I should disable CORS on my blog, then! I normally use a dedicated feed reader, rather than a browser, but it makes sense to accommodate both use cases.
