This sucks. I'm not saying it's not the answer, but the fact that you have to castrate your feed because spam sites can actually get "SEO credit" for your content just sucks. I always loved RSS feeds that published the full text, because I could read whole articles without having to click through.

Semantic web could fix this a little by making it easier to scrape with the <article> tag, but publishing content is exactly what RSS was meant to do.

I wish Google would (if even possible) find a better way to fix this. In the same way that there's an actual argument against single page apps because "they can't be indexed" or "SEO, man." Discoverability shouldn't be holding back progress (in an ideal world, I know). Rather, indexing should adapt to new technology so that we can make a better web that's still discoverable by users.
