Not good for RSS

ReadKit works with almost a dozen services, but I was hoping to use it primarily as a RSS/Atom reader, which it does poorly. Most other RSS readers do a better job with invalid RSS, or at least give some warnings, but this failed to properly process some completely valid feeds. If you want an Instapaper client, someone else can tell you if this is any good, but for my use, almost every other feed reader works better.
