Hi, I work for Superfeedr. We do feed parsing on-demand. We don't care what feeds people are giving us to fetch. As a matter of fact, we don't even care about the content. Yet, some users have given us RSS/ Atom feeds from Twitter to fetch.
We bumped into the polling limits a few months ago : we asked to be white-listed and "gained" a few month. We now have about 15k Twitter feeds, and polling is not suitable anymore. We implemented your streaming API to make everybody happy. Except that it deosn't work. : we get "413 FULL head" errors. I asked Ryan Sarver for help, he granted us a "shadow" role, which is really not what we need. What can we do? Thanks
