Content discovery and curation for RSS were the issues that startups like Technorati focused on. Their failures were partly failures of management. My startup wanted to build its business using Technorati data, circa 2006, but their sales strategy was bizarre. The API was supposedly pay-for-use, and I was happy to pay, but instead of offering an automated system for creating an api account, they asked that you write to their sales team. I wrote to their sales team at least a dozen times, and I tracked down the personal email address of the CEO, but no one ever responded to me. I was convinced then that they could have made a lot of money if they had made it easier for developers like me to give them money. But they made it impossible. And now it seems they gave up on RSS aggregation. They seem to be in a different business now:<p><a href="http:&#x2F;&#x2F;technorati.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;technorati.com&#x2F;</a>
