“Who will be left standing?”

Dr. Drang makes a great point about what can happen when Apple moves into your territory (using the recent WWDC announcements and Instapaper as examples). His point is not that these apps have things to fear, but that they should fear Apple putting effort into these categories. If Apple puts a modicum of effort into the reading list offering then there most likely is reason to be concerned for services like Instapaper.

Great points.
