The last few days have been pretty intense for Samuel Clay, developer of NewsBlur. 60,000 new people have signed up for his service, 5,000 of which have become premium subscribers. This is more than double the previous number of 50,000 users. Incredible.
I've been checking out NewsBlur myself (using the live demo at the link above), and it looks fantastic. Once he has the scaling issue figured out, it might just be amongst the next group of killer RSS services.
