Some quick research for Pocket replacements.

I chose Instapaper, with a free account. I exported my Pocket data (.csv file, arrives as a .zip via email), and imported it to Instapaper via the Settings menu. My Pocket items aren't showing yet: don't know how long that normally takes. Instapaper's website seems kinda squirrely - several 500 errors: maybe they're getting slammed by Pocket migrants right now?
