How many of you actually use cha cha search engine  

I wanted to be a part of cha cha but I was told that I had to be invited. For me, I use google.

I am a cha cha guide myself too. I am part of the cha cha mission so I use the cha cha toolbar to search often. I also search with a guide from time to time mostly to test the system and see how efficient it is. Unfortunately, many people got gung-ho with invites early on, and there are guides that look at it as a way to earn fast, and take little time to read up on the code of conduct, the training checklist, the handbook, view the videos and they are just interested with getting as many searches as they can--those types give a bad impression to the infoseeker and this makes Cha Cha look bad, and makes it the unpopular choice for doing your searching.

The bottom line is, if you know how to use a search engine properly, you can find everything you are looking for and it doesn't matter what search engine you choose to use.
