Though a dating site makes for a great platform to fall back on, in the event nothing comes to fruition with the name, you can always create a blog of some sort, if you do not wish to get into the dating site niche alone or at all. I am just trying to think outside the box here with a few general ideas.
I hear it all the time from folks (both male and female) that as they get older many feel meeting people and dating become more difficult, as does love in general. Many folks feel they lost their proverbial game, style and hope, while others never had it to begin with. Their mojo is gone, in other words, often leaving them to wonder if in fact true love really does still exist. Many feel meeting people in the real world can be somewhat tricky, and often need ideas on how or where to meet or attract someone of interest. Perhaps a site that offers folks methods, tips and ways to meet people in their day-to-day life, rather than online life.
Perhaps include a type of advice column or offer tips on how to be successful in dating, love and general relationships, for different age groups, cultures, races, sexes, etc. How to get back into dating for those who have just ended marriages or lengthy relationships, or those who have spent a lengthy period of time working on their career, raising their children, etc. Offer ideas or themes on proposals for those looking to "pop the big question." Maybe even have different chat rooms and threads for folks to use.
The name even holds religious undertones if you were so inclined to go that direction with it. Additionally, it doesn't have to include romantic love between two people, but rather, the love between humans who help those in need, such as a donations site, random acts of kindness, animal rescues, helping the homeless, lost or missing children, etc.
Just a few ideas that came to mind, some of which will hopefully help. Nonetheless, best of luck with the project. Do keep us posted once you get something put together.
