Mobile Industry Review tests “Pocket vs. Instapaper”. I’m seriously looking at Paper, as I’m starting to loose count of how many times I’ve seen this frustrating notice from Instapaper, when trying to save out a Kindle .mobi collection of articles. The worst of this is, the wording suggests the user has done something wrong. When any regular user knows that it’s Instapaper that’s failed. If Instapaper can’t keep their servers online, and insults their users during such failures, then why bother with it when there are alternatives?
