My top suggestion would be if Bing improved its spidering vs indexing. Bingbot is busy, but it often doesn't find the updates and changes.
My second suggestion would be new sites. It just doesn't pick them up fast enough, if at all. My suggestion would be that they index the new material, then, if after it's failed to meet the minimum levels required, it drops down the ranking. At least the new site would have half a chance.
Note, i'm not talking about spam, i'm talking about genuine sites. The spam filter should deal with anything that isn't legitimate.
Perhaps those two things are tougher than we think to implement.
Any other suggestions for the Microsoft Bing team?
