As an aside: This is why nobody should care about how unique an idea is. Just being unique won’t help a startup, and the ones that think they’re the most unique are usually the ones that are the most likely to fail immediately. Last week, the community at /r/Entrepreneur settled in to figure out which startup ideas fail the most often. Here’s the cream of the terrible idea crop.

Starting a Bar

An App for Business Cards

Crowdsourcing Good Ideas and Selling Them to Companies

The Next Facebook

Apps to “Fix Travel”

Social Media Aggregating Apps

Okay, this one’s mostly my own suggestion… but plenty of them have failed in the last few years, yet they keep popping up in new forms, like Circa and Facebook’s new apps, which both folded recently. People download an average of zero apps per month, and they already get their news from the social media accounts that they’re already plugged into, making it incredibly hard to tear them away. It won’t be pitched as that though.” ~swivelmaster
