Our clients love Loudervoice for two reasons: 1) the feedback that it collects which is nearly always very generous in praise for their services 2) this feedback collected on the website is then automatically posted to the reviewee's facebook and twitter accounts as well as the pushed to client's facebook page. A really simple way to join website and social media presences and provides effective 'word of mouth' referral marketing.
Adding to an existing website or blog is very straightforward and Loudervoice is very cost effective.
Two examples are http://www.ohhcompany.co.uk/the_northey/reviews.html and http://www.onoto.com/testimonials
