I think your first heavy users will need to be people who are putting brand new products on the market and have no idea how they are going to get feedback. People who have been making iterations for years will have a bunch of work in the past that they won't get 'credit' for, so they might not be fans of starting with a blank slate. Maybe if you had a way to import or track feature requests from other feedback sites, that would get you more users. It's worth noting that you are competing with other bug tracking / feedback web sites, and there are some established players there.
