IMHO, forums such as this should practically pay members, not the other way around. The only value of the forum is from the input provided FREE by members (just like facebook and all the other social media sites). No members, no value, no ad revenue. You can see why I find it difficult to fit into society with my perverted thinking.
Other companies have had more success, however, and Duck Duck Go is not the first search engine firm to tap into the pro-privacy market.
Competitors include Ixquick, a Dutch meta-search engine firm, based in the Netherlands and New York. It returns private meta-search results from other providers.
