comScore just posted their search share numbers for January 2008 and it's bad news for Yahoo.  Yahoo took a 0.7% hit, while Google got a small 0.1% bump.  Windows Live remained the same as last month, so there is not much to report there.  Even though Google's search share rose, it appears that Yahoo's lost share went mostly to AOL and Ask.  The real question is whether Yahoo's share will continue to fall, or if this is just a fluke.  After all, Yahoo was up 0.5% the month before.  With a potential acquisition on the horizon, you can bet that everyone will be watching these numbers closely in the months to come
