Interesting new data comparison engine site, launched by DoubleClick founder Kevin O'Connor. FindTheBest.com is stil in beta, but is clearly very useful. US-centric data restricts it for now, but try this for comparing blog software, or this for learning more about plants.
"You can find anything on the web but it can take you hours or days of
research to compile it into a useful form to make a decision. People
need objective, factual information in order to make side-by-side
comparisons in order to make the best decision. We've created the first
broad-based comparison engine to help people make informed decisions
quickly."
"FindTheBest is a comparison engine that allows users to find a topic,
compare their options in a side-by-side chart, sort and narrow data with
smart filters, and select the best choice based on what's important to
them. This all happens inside 'Comparison Apps' or 'Apps', which are
presented in the form of filterable charts."
