This is very true, honestly when you think about it you really are giving a lot of time just for "ego stroking". Implementing a nice high level tier of benefits for those who contribute the most could be great. For example if you reach a certain threshold of generating content you get entered into a premium tier where you receive a once a month voucher for things or whatever it is. Business's could give these deals to the service too since they'd be rewarding their most adamant customers who are also the ones who would be spreading the service through word of mouth. Sure it takes a bit more work for the service but user engagement would benefit tremendously.
