I like the idea behind MarryAgain.in. It's an Indian matrimonial website that focuses on a certain niche. Those who've been divorced or widowed can seek remarriage via this free site. The advanced search function is interesting. You can search by previous marital status, religion, family values, children, and even income. Given that the divorce rate in India is growing, I think it's a great idea to run this type of website. What are your views?
