The new Bing.com (here) online search from Microsoft went live this morning; a quick check found results for DiscoverET.org showing up approximately the same as on Google. Search Engine Optimization(SEO) for websites may be roughly comparable, but its likely too soon to tell. However (for what its worth), we discovered that Google had "crawled" DiscoverET.org a day more recently than Bing.
Bing.com is replacing the search formerly known as Live.com's search engine. Its a pretty interface--but we found it loads in the browser slower than Google . What impact will this have on Google? We'll wait and see.
