Search Engines

I have temporarily skipped the podcast thing because I would like to give more time to it than I actually have time at the moment.

So, search engines. I am a Google user. Every now and then I use Yahoo, but not often. I did the same search on Rollyo, Mamma, and Dogpile. I pretty much got the same results each time. I don't necessarily see the advantage of any of these over Google. Granted, I didn't mess around with the customizable feature in Rollyo. If I dug deeper in Mamma perhaps its special features would shine through also. So, to put it succinctly, I need to do more comparisons.
