I think it depends a lot on the phase the start up founders found themselves in. If the concept is concrete enough and the road map is more or less finalized, it might be a good idea to talk to your trusted friends and family members. It's true that the initial road map the founders decide, keeps on changing as the idea evolves into an application and the further development is done based on the feedback stream obtained. In my opinion the founders should keep themselves open to the idea of incorporating a few more people who love working in start up situations. These people can also be a part of the initial team once the start up gets funding, only if one is looking for.

I think the tag cloud is self explanatory in the sense, the font of the individual tags depends on the amount of content under a particular tag. It's a visual representation of the category system where the amount of content in each is represented by a number in brackets in front of each category. Both these techniques have their own pros and cons as one is more visual while the other asks the user to find out where he wants to go. I think a combination of both might be the optimum solution, where the content is provided under tags which are pretty broad and category and sub category takes the user deeper and is more useful for users who are looking for specific information.
