Lately, I've been putting together a list of things that make social apps viral, mainly looking at the startups that inspire me most in that area (social). So this is loosely gathered from looking at Hashable , PlanCast , Quora , Foursquare , LikeALittle and the likes. It's just a candid look at those - and others in the same space - startups to extract what might have been part of the essence of their viral growth. In other words : they all include some or all of the following points. What this list is : my thoughts on the (killer) ingredients that can make your startup viral if you have the first mandatory ingredient : an interesting concept .
Cool post, but there is one thing I disagree on: focus on just one use. Facebook, Twitter, Foursquare and more recent servives such as Instagram (not to mention pearltrees) all have different uses. That's precisely what make those services social. Of course, this trade-off with simplicity, and that's why making a great social app is so difficult. by Jan 11
