Ironically I had just finished publishing a blog post (<a href="http://jeffmould.blogspot.com" rel="nofollow">http://jeffmould.blogspot.com</a>) on why I don't think Bing is quite there yet. Their engine appears to have a bug somewhere that doesn't index sites unless you have numerous backlinks to your site. While some may not consider this a bug, it makes it difficult for the little players (myself being one) to be included in a real time search engine. Google on the other hand had indexed my blog post within 30 minutes of me posting it.
