My three emd's have been sandboxed by google for a long time. My improvements to the sites do nothing to impress google, but apparently do impress Bing and Yahoo, because the homepages and several internal pages of these sites have risen up nicely to pages one and two on these other search engines. It's enough to give me a trickle of traffic, and some Amazon sales.

I had been seriously considering going to webmaster tools and having the all the urls removed, so I could put the content on new domains, but am not sure about that now.

I guess I'm posting this thread to get some opinions on whether or not I can expect Bing and Yahoo to hold steady with these rankings, or are they liable to act like google at any point. and sandbox everything.
