I’m not sure Jewish scholars such as Maimonides, Hillel, Akiva, or Rashi would be able to agree on whether it is better to have a vague ‘In My Own Words’ answer… or a more detailed one (they didn’t agree on much, so it’s not surprising that our people are known for our argumentative nature).
On one hand, a vague About Me (or any other category) is enticing as it leaves more for your date to discover on their own and allows you to let them discover more about you at your own pace. You get to reveal more about yourself in your (few) emails, a bit more in your (10 minute) phone calls, and even more in person. You’re not putting everything on the table, and that means you don’t have to live up to any hype you create if, for instance, you are really funny with your writing, but not so much in person.
On the other hand, being more detailed in your biography means that the prospects you attract know exactly who you are and what you are attracted to — more than just your photo and a few general tidbits. It means you have likely weeded out potentials who you may not mesh with, but it also means that you could have eliminated quality prospects who think you are too set in your ways… even though it’s not only acceptable, but more enjoyable to not agree with each other about every topic.
So here’s where your How to Woo a Jew scholar gets to butt in and give her two cents… I suggest a happy medium. Some areas you can stay vague while others that you feel more strongly about should be more detailed. If you are sarcastic and witty in-person, then try to convey that in your biography. If you love debating politics, then say that as well but also mention some particulars — if you are a staunch Democrat and couldn’t bear to be with a hardcore Republican, then let that be known! Areas where you are open to exploring should be left vague or simply state that you want to learn more from someone who is an expert or enjoys those things.
Basically there’s no “right” or “wrong” way because everyone has a type, and the person for you won’t be turned off by your vague or detailed profile… the caveat here is that if you’re having trouble meeting quality prospects, then it would behoove you to adjust your answers towards the other side of the spectrum.
