Wize is a site that combines expert and user reviews with a focus on consumer electronics (and a few other categories: Home & Garden, Health & Beauty, Video Games).
They compile professional reviews with user ratings to come up with an overall rating.
In their About Us section, they describe: “Because it’s based on user and expert reviews and rankings from thousands of independent sources, Wize Rank is completely impartial, and cannot be manipulated.”
Metacritic has also been doing this for a while in the realm of Music, Movies and Videogames.
Tech Crunch calls it Aggregate Reviews and they have a roundup of companies doing variations of this here.
I haven’t seen this proposition for a city guide yet. We don’t intend to aggregate pro city guide reviews, but we do consider our roster of personalities to be expert NY insiders and editorial contributors. Coming up in our next layout (in June), we’ll enable user comments and ratings so our audience can also weigh in on the featured recommendations.
You can even mix some flowers into your vegetable garden to make it all the more beautiful.
