Earlier this week, I wrote a column in the Financial Post exploring the idea about whether a new rival to Google in the search market could emerge. My take is it's unlikely unless a company develops kick-ass technology and has the financial backing to build a global brand, large user base and, as important, the back-end infrastructure. An interesting angle in the search story is Dipsie, which initially wanted to go head-to-head with Google in the mainstream search market but has decided - at least for the time being - to focus on the deep search market (data hidden behind firewalls and databases). You can read my column here. SiliconBeat has some more details on Dipsie as well.
