Instapaper for iPad updated with smart sorting features

Aside from a few visual tweaks that help it to better fit in with iOS 7, the biggest update is the new sorting options that allow a reading queue to be filtered by article length, date, or popularity. Though Instapaper hasn't changed drastically since it was purchased by Betaworks earlier this year, the startup has now issued updates for every platform that it's on — fairly quickly breathing new life into one of the oldest read-it-later apps.
