Here is another move by a search company to partner with an established site. The deal is estimated to be worth half a million per year for a community of 13M users.
From an article on Stuff, a New Zealand news site:
Eurekster president Grant Ryan says the contract will bring in "at least mid-six figure" revenues per year and is the biggest deal the company has secured so far.
Thanks to the deal, Mr Ryan expects Eurekster to be cash-flow positive in a few months.
