Some people guard their privacy online jealously. As much as they want free email and facebook, they shudder at thoughts of having their data scraped, email addresses exposed, and photos indexed. But the trend of web services is not in favor of these digital hermits. More and more social networks and applications are popping up, allowing users to trade their personal information for cheap and amazing services. One such service – Blippy.com – is like a Twitter for your debit card. Sign up with Blippy, and you can immediately and automatically share info about what you buy, watch, and listen to with your own social network or the whole world. David Hornik loves Blippy. He loves the trend towards radical transparency. And as an investor with August Capital – who’ve helped give life to successful startups like evite and stumbleupon – he’s got his eye on where this trend could be going. And by the way, you can follow what David purchases at his public blippy account.
