Ha, similar stories - I&#x27;m aware of Technorati, they really should have been the firehose of their day (I guess Wordpress.com is the closest thing now). I was building a feed reader that would cluster conversations around the blogosphere so you&#x27;d get a better sense of the daily zeitgeist than just following quotes or trackbacks. Which brings me to the more direct comparison - comments and trackbacks to replies and retweets. Finding new content branching from what you&#x27;re already reading, and frankly the experience was just clunky and terrible compared to Twitter. And that&#x27;s assuming you&#x27;ve even _found_ a feed reader and subscribed to some feeds. And even if _that_ was easy, where are you yourself publishing? Every task was harder, and only Tumblr has really come close to replicating Twitter&#x27;s level of integration on a blog-like platform.<p>Tons of Twitter&#x27;s best features were stumbled upon by accident, but a lot of their decisions, especially around limiting third-party clients, were justified in their minds by their user testing that showed just how confusing it was to locate and install a useful Twitter client and sign up for an account. The control they had allowed them to reduce friction to nearly zero. For anyone like Technorati to replicate that with open standards, they would have just exercised the same level of ownership.<p>This is all a shame, I&#x27;m sure there&#x27;s some alternative universe in which longform content has been saved from invasive advertising by a frictionless, open system. And I certainly don&#x27;t think Twitter is going to come up with a particularly interesting or successful business model. But I open my Twitter app more than my feed reader, and I think I&#x27;m happier for it.
