I not only miss blogging, but RSS feeds as well. Seems like everyone is ditching it in favor of Twitter and FB
When I look at this through the Clay Shirky "publish-then-filter" mindset, what I see is that we have a problem with our filters--whether those filters are RSS aggregators, search engines, follower lists, inboxes, subscription services, it doesn't matter. Look to the work of people like Paul Ford (@ftrain) and little hacks like SavePublishing.com.
Solving this filtering problem and creating a focus of attention--that's a huge opportunity. Not Uber huge, or monetarily huge, but huge as a public service to free up the mental capacity of a lot of talented people whose filters are very likely tuned by default to the commercial aggregators.
