real time search is useful and probably monetizeable, but extremely niche. i have heard plenty of examples, like some described above, where i've felt "yeah, ok, i could see that." but those times when it might be useful might occur twice a year, maybe 3 times a year? so the market is incredibly small. it is most certainly not a threat to google, in my opinion. i am shocked that oneriot has raised $27M and only have a few hundred thousand hits a month. i think real time search is way overvalued in terms of growth potential, and will probably find equilibrium as an occasionally useful niche utility.
