411.ca

For anyone who utilizes the Internet to search for things located in your city like places to eat, auto repairs, clothing retailers, etc, there is a great new free to use site out there: 411.ca

411.ca relies on patrons of all types of businesses to post reviews and opinions (also free to do via creating an account), which others can then skim through to see what people think of a particular place and learn of the hits and misses in the city.  They also offer a white pages option where you can type in a 'person' and are provided with an address and phone number. 
For the contributors of 411.ca, you are rewarded for interacting on 411.ca (IE writing reviews, rating reviews, etc) with 'Influence Points' which basically increase your 'level' over time.. Basically bragging rights, that you are a top contributor.

My opinion of 411.ca? 

The ability to see reviews of businesses is invaluable.  I had to find a new mechanic last year and had a very difficult time trying to figure out WHERE to go, as you hear so many horror stories out there of shady places.  I (luckily) found a great place going in randomly, but could really have used a site like 411.ca to help guide me in the right direction.

The 'person' search (white pages idea) is lacking.  I entered in my own self, a relative and friend and all three of us had incorrect information - two incorrect addresses (Two moves that occurred over 5 yrs prior) and incorrect phone numbers.  I guess there is some work to do on that front!
All in all, a great site to check out if you are interested in seeing what others think of a certain establishment before you head there!
