@johngordon Yikes (Pushpin author here). Easy way to check. If you're familiar with the command line, I wrote a Python client to interface with the API. "pip install pinboard" → "pinboard login" -> "pinboard bookmarks"
@andyw (BIAS ALERT: I write Pushpin) Here's the short and sweet why I think $10 is a good deal: 1) it's universal (two apps in one!), 2) it contains a lot of features other apps don't have, and 3) we will never charge for an update, ever.
