When Bing launched www.bing.com/social (Bing's combined search of Facebook and Twitter updates) back in June, it forgot (I presume) to update its robots.txt file (which had previously, and still does, disallow results from the more limited forerunner - bing.com/twitter). As a result, 154,000 pages of its search results are in Google's index.

Bing says xRank is "an insightful ranking formula that tells you who the world is searching for most. The result is a cultural snapshot of who's hot and who's not!"
Er, no. It currently thinks Ash is the hottest band around right now because people are searching for volcanos.

I've been trying to get people I work with to stop filling out meta keywords fields for ages, with varying degrees of success.

Google has come out and said this: "Does Google ever use the "keywords" meta tag in its web search ranking? In a word, no."

If you use Bing USA, you don't just get more features - you get to see how Microsoft paints Britain to the Americans. It's not a pretty sight as these screenshots show (they also show that nearly all UK-related terms searched for in Bing USA return wikipedia first or second) .

A rundown of the differences between the UK and USA versions of Bing (presumably we'll be getting the missing stuff soon).

Microsoft seem to have reacted badly to my post on the usability of bing - someone left a comment defending it without revealing they were a Microsoft employee (which is illegal in the UK). And they've either manually deleted the post from the bing search results or it's taken them more than 4 days to index it ...!

bing is a usability disaster - confusing links allied to unusable functionality. And is it called bing or Bing - make your mind up Microsoft.
