Need a date? If you’re up for the whole online dating thing, try SocialGrid. It’s free, for starters, and it claims it will remain free for the long run. How they work: SocialGrid uses a search engine based on Linux clusters which is designed specifically for finding matches. Rather than rely on membership costs, SocialGrid will share traffic and shifting costs to other sites with personal pages and blogs. Their search engine is based on low cost grid computing and enables users to search for people based on their profile information—i.e. interests, personal traits, characteristics, income level, age etc. Users can search for people with similar tastes and characteristics all over the internet regardless of what social network or community they belong to, as long as they have a profile. Contacting other people is of course free, and the site implements a strict spam policy.
