As a single person wandering through the world, it can be difficult to find someone who loves all the right things: parks, subways, bike lanes, human-scale buildings, high-density housing, debates over the ideal length of a city block. Even on a dating app, you can't always tell from a profile who might be thinking, behind a smile, I hate cars. But if this is exactly the sort of partner--or friend or fling--you're looking for, there is a solution: Join the wildly popular Facebook meme group and leftist community NUMTOTs ("New Urbanist Memes for Transit-Oriented Teens," which isn't really just for teens) and request access to its private spin-off group, NUMTinder. With about 8,000 members living mostly in North America, the United Kingdom, and Australia, NUMTinder is a makeshift dating environment for those who consider liking public transportation to be a core part of their personality, or those for whom a lack of interest in urban planning is a deal breaker. Almost everyone in the group posts at least one selfie with a bike or a subway entrance to demonstrate commitment to the lifestyle, and when a new member introduces herself, it's not uncommon for her to brag about the fact that she doesn't have a driver's license.

Scientists say the secrets to success in online dating are to aim high, keep your message brief, and be patient. Playing "out of your league" or dating people considered more attractive than you, is a winning strategy, according to a new analysis of internet daters in the US. Men had greater success when they approached women they believed were more desirable than themselves. The new study has been published in the journal, Science Advances. Internet dating has become the dominant form for those seeking romance - it's the third most popular means of meeting a long term partner and around half of all 18-34 year olds now use dating apps.

But don't worry, you're not alone in this. We compiled 13 spot-on stories surrounding online dating, ranging from blog posts on personal experiences to expert advice on the do's and don'ts of the game.

Around the world, 91 million people are on dating websites and apps. Finding "the one" among them may seem daunting - but some tips based on scientific research might help, writes Dr Xand van Tulleken. I'm 37, and for years I've been dating in London and New York, looking for Miss Right. Some people enjoy being single but, perhaps because I'm an identical twin, for me it's purgatory. Nonetheless I found myself single having - wrongly I suspect - prioritised work and travel for too long.
