Check out this thread from April that has a couple comments from Sam: Twitter API disabling free access - #20 by samuelclay
It sounds to me like the API price is too high (best he can afford is Hobbyist, which is just not enough) and he says if you really want Twitter+Newsblur you can host your own Newsblur instance and get your own Twitter token. Others in the thread pointing out feed syndication apps that have had their tokens suspended for violating Twitter’s new TOS. Sam might yet chime in to the contrary, but personally I’d suggest preparing yourself mentally and emotionally.
