I recently logged in to the Diners Club extranet to check the credit card balance after our trip to Provence, and noticed a new feature there. They had picked some restaurant bills from my credit card statement and asked for me to rate them in a very typical Web 2.0 fashion:
</span>It will be interesting to see what they will start doing with the ratings. Netflix-style recommendations of restaurants people with similar tastes like would actually be quite useful.
A question however is whether just silently providing this rating feature on their site is enough for getting people to rate restaurants. Maybe they could query for ratings in their newsletter a bit like Netflix also does.
In any case, making a mashup of the ratings from Diners Club and location and opening times information from eat.fi would make a perfect “where to go for lunch?” solution.
