Even biotechnology company is building up social community. 23andme, a newly startup biotechnology company is offering Personal Genome Service, the service cost USD1000, they will send you a kit, follow the instructions, send back your saliva sample. They analyse the DNA and help you to find out more about yourself, they can help you on friend matching by DNA as well.
23andme is not the only company provide such services. In a news title, 'online dating site offer DNA matching', the story tells a company-- Scientific Match, use DNA to look for a match for married partner. For me is more like, 'Biotechnology company offer online dating service'.
23andme is a privately held company. Google has invested 3.9 millions into the company a few months back. Anne Wojcicki is the co-founder of 23andme, she married to Google co-founder Sergey Brin. Now you should not surprise why Google invested in 23andme, with 23andme join in the social community website, it make more sense.
