Just how much are people talking about Justin Bieber? How ga-ga are they for Lady Gaga? Viralheat has a platform for tracking these sorts of social trends and now the data in over 4,000 searches is available for free. Today the company announced its new Social Trends endpoint for the Viralheat API.
Defensio, the anti-spam service, offers an API that can be integrated into blogs and web sites to fight spam comments and other unwanted spam (details at our Defension API profile). The service appears to be run by a small team, and is similar in purpose to Akismet, the much larger spam filtering service from Automattic (which powers WordPress.com), who also offer an anti-spam API.
