If you are reading the blog of a Microsoft developer, you shouldn’t be surprised when he posts examples using Bing. While I’m all for open source, and convincing people to switch, an MS blog probably isn’t the place to complain that Bing throws a warning in Konquerer and that Google Maps “just works”, especially when Bing works fine in Firefox, and the only reason you’re seeing that warning is because you are using a somewhat niche browser (yes, I realize that it’s essentially Webkit, and that if Chrome and Safari work, then it should, too).
As he responds to one of the comments – “If I link to Google, people scold me for not linking to Bing. And now, if I link to Bing, people scold me for not linking to Google. … I guess the only safe thing is to not link to anything.”
