In an interesting interview over at Read/WriteTalk, and as noticed by the ProgrammableWeb, Twitter’s founder Biz Stone claims that Twitter API has 10 times the traffic of Twitter itself.
This doesn’t really come as a big surprise knowing how many cool Twitter-related apps exist out there, but it definitely shows the importance of having an open API. The list of companies which have gone this route and practically wiped out the competition is overwhelming: think Facebook, Google Maps, Digg, Flickr…
Twitter’s biggest competitor, Pownce, still doesn’t have an open API; they might want to hurry up or face the fate of always playing second fiddle to Twitter.
There’s another cool api here, that allows you to set up accounts for your app automatically, http://www.widgetplus.com
