Salesforce.com have set up an ideas section within their site that runs like Digg. That is, the most popular ideas float to the top.
Software companies have been running user forums for many years, and typically the customers with the highest budgets got to dictate the priority of development releases. Whilst it is important to look after your best customers, this new site allows for anyone to suggest a new idea or enhancement for the product.
Perspective: One of the things Salesforce.com does well is service remote based sales people, and this is another example of ensuring that everyone is given a voice in the development of the product. Afterall, sometimes the best ideas come from places where you don’t normally look.
