Search engines gone beserk?

I wrote in an earlier post about Spacetime and how cool I thought it was. Well someone just upped them with a browser-based version of the same concept: SearchTime. Amazing how much easier it is to find the right result (but also slower - I think? - enter the debate of perceived speed). Another interesting user experience is Oamos. I'm not quite sure what to think of this from a user perspective. One thing is certain: it isn't very effective in getting me to what I need - but I do get an experience along the way.
