The key is whether dinking around with the content and even dropping elements that are less likely to appeal to mobile users - most notably text paragraphs - will hurt the existing (desktop) rankings.
It hasn't for me. I really like responsive design, but I think it's only a partial solution, because I'm pretty sure that mobile users use the web significantly differently than desktop users (and there's probably differences between phones and tablets, too) At least, my users do. So a responsive design is great for getting your entire site into more formats that can be easily read, but it doesn't really take into account the differences in the ways that users read and navigate your site. So I ended up with two themes anyway.
