I think it makes a difference if you can get permission to use a name, or their website along with the quote, so people know the comments were real.
I did something much like this on my web sites
Here's a sample-

Just a pile of simple quotes, and a way to let people know they were real.. because anybody could type in a bunch of great compliments and give no way to back them up..
Just a thought if the option is available
..and this reminds me that I need to get in there and get these updated from recent clients..


I do not work here, but the benefits are still awesome
