Google gears up to repel boarders ... again.
Scoopler: Real-time data is their USP (Scoopler Blog: http://blog.scoopler.com/). Good luck, guys - hope the first tranche of investor money lasts long enough to get enough traction to sustain you.
Bing: owned by Microsoft is their USP (Maps go to Multimap, Shopping goes to price comparison engine Ciao). Why do we need pretty pictures? Big G and Colliris (Firefox pics) work fine for me.
BTW, don't try to search for Scoopler from Bing - no results. Google, of course, finds it.
Update 15 Jun: yet another search engine launches, this time a 'kosher' one: Koogle, 'for Hebrew-speaking Orthodox Jews'.
