Months ago, I submitted my sitemap.xml to Bing. I check the webmaster tools all the time. No errors, it sees all the links in the file and reports the correct number, but it refuses to index my pages. I do a search for my site in Bing and it shows me next to a bogus social network site of a similar name. All the while, Google is continually slurping up my content and showing my site correctly in search results. I appreciate the promise of Bing, but I think the implementation still has a lot of work to do.
