Brafton's editorial reads like a press release from Mircosoft Bing. The premise is that Bing is growing in the month of August and that Google is losing market share. The analysis of Bing being a contender seems very premature considering many technical people reviewing their analytics will see a minute portion of their traffic comes from Bing vs. Google.
This kind of promotion is unlikely to make developers make the switch, but I am interested -- maybe the short-term lose of Google could be explained by the gain of Duckduckgo. That's the bias I would editorialize.
