Google's RSS Reader webapp is shutting down. Starting July 1, the service will no longer be available to users. Google claims it is due to low numbers of users and activity, but it seemed to be one of the more popular RSS feed readers out there. Broken hearts all over the internet are gearing up to switch to something new; Google is allowing favorites and feeds to be exported using Google Takeout.
Google killed Reader' sharing/following feature a few years back, and is now doing away with the whole thing. Some users are petitioning Google to keep Reader alive, or at least release the source code.
