I didn't know the RSS feed could be styled - it's an interesting insight.
That said, on the RSS as a whole, for most websites (mostly publications I suppose), adding RSS feed is a set-and-forget thing.
Sure, it's great for readers as it allows them to read all the content from one reading app but, on the other hand, the publication can't provide a custom experience, or - what's most important for some publications - display ads. That's likely why RSS is slowly moving into obscurity, at least IMHO.
