Last week I noticed that my inbound links dropped by 90% according to GWT and this morning my traffic is reduced by 50% although I did retain my top rankings on my hardest earned keywords.
It looks like LESS links are being deemed worthy and so your rankings drop depends on how dependent you were on those links for you rankings.
LOSS OF SPECIAL RESULTS The search results look oddly cleaner in my niche. ask.com, yahoo answers and ehow are all newcomers so I'm not referring to quality but I've lost my "special" rankings (ie: multiple pages linked) so there are more sites above the fold now.
