One of the big downsides of being an early adopter is that you start using or depending on technology that gets shutdown from lack or success or acquisition, like SnapJoy under Dropbox. I didn’t use Snapjoy but there have been others. I was a big proponent of Oink. I also used LivingSocial to track beers, apps, books and movies back before they dived into the world of daily deals and local marketing.
