I think you could definitely white-label the DomainPolish idea and sell it to people hoping to build a Review X service. The problem is that if you just try to build a site yourself that lets you review anything it's very difficult to target your customers.
People search for "get feedback on my website" not "site to review anything". Picking a specific vertical makes marketing much easier. But it's a cool idea! I can put you in touch with the current owner of the DomainPolish source - he'd probably license it to you :)
If you were going to do the 'review anything' concept you'd need serious marketing cash. You'd also build verticals within the service to target, to benefit from search engines and try to narrow on the big core markets (but still stay open to literally any kind of review someone might want to do). Same way Oracle etc customizes their business software "solutions" for verticals.
I'm terrible about that (the licensing idea), I'd be far more likely to just code it from the ground up, even if that's the stupid monkey approach. I like having a personal relationship with my code (lol), the structure of the site, and knowing how that correlates to projected scaling, and so on.
