It's not on my site. It's because I'm trying to link directly to the favicons from the original site. I have a fix shortly (caching favicons locally). That also fixes some of the sites who prompt for logins when the browser tries to pull the favicon. Thanks for reporting it.
Not yet, but great idea, at least for the larger countries when/if they have a sizeable Twitter base, and assuming the language can be sniffed out fairly easily (well, the asian languages should be easy...).
It summarizes/ranks links being discussed on Twitter, not simply by looking at the tweets, but by visiting the destination sites being pointed to. It was written as a testcase for software I'm writing for streaming realtime financial data (prices and graphs) to modern browsers, but I've grown fond of it since. It's for people curious about "what's cooking" on Twitter.
