Thank you, Brinked, for bring that up.
I was hit by the March 23rd, 2012 Panda (and further whacked by Penguin) and I wonder what the effect of 301 redirects are.
I moved half the content from Site A to a new site (Site B) in October 2009.
Site B had been doing quite well in terms of increasing traffic (but it is NOT a competitive niche).
then as I mentioned, March 23rd panda chopped about 30% of traffic off.
I am thinking of removing those redirects because they are all still in place. Those old pages will just return 404 responses then.
Maybe that will appease the master?
