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.
I agree, but with sites that do not have much authority (aka PageRank), it's difficult to determine attribution when scraped content is coming online just as quickly as an original post. Googlebot will generally hit a site several times a day, but if it's hitting the spammer's site first or if the spammer site has more authority, it's a long uphill climb to get things turned around.
I should also point out that this is just one thing to consider amongst the other points already made by others.
I must admit, I'm not desperate enough for new readers to hamstring my own publishing to my existing readers - so summary RSS feed is out for me.
I'd consider delaying RSS publication but that's actually very awkward as it's an Octopress website (i.e. created and pushed as a set of static pages, including things like the rss feed).
