Is this an example of a company that uses a defender strategy?

A company that uses a defender strategy sticks to what its good at. If you meant is answers.com is a defender company i would have to say no. Most of this user created content pages rely almost entirely on adverticement which is a distinctive caracteristic of a prospector company. Take google for example the argument could be made that they are defenders since they base their whole company around search engines but in reality it is a prospector company because of all the different industrys they touch with their program and their hundreds of aps. Wiki is similar as i see it and while this exact page only deals with answers to questions its still attempts to expand on their product. Hope this helped :-)
