A couple of reasons this will probably not work.<p>a) Categorization of interests. I think it is pretty hard to come up to something that really captures this. Example: I bet that maybe 80% of users of a dating app (any dating app) will select &quot;Art&quot; as one of their interests. 
It does not matter if it is true or a ploy because the user shares my estimate that 80% of users will select Art anyway...  ok, you selected &quot;Art&quot;.
What kind of art, now? Note that to offer the right &quot;adventure&quot; the system must also be able to distinguish between a Exhibition of Paintings by Monet, and a play by Chechov. These are both about Art, after all.<p>b) What about things that you really enjoy (like reading books about programming) but are mostly enjoyed alone?<p>c) What about stuff you do in groups, but don&#x27;t really allow you to focus much on the other person (to discover if you actually are interested in each other)? Like going to a Martial Arts seminar, for example, even if you both happen to love the same kind of Martial Art?<p>I think that the whole idea is based on &quot;I want to date someone which shares at least one of my main hobbies&#x2F;interests&quot;. And makes its job harder because it tries to find out stuff to do together and therefore it has to know about seminars, schools, movies, places, events and any other thing that could serve as a &quot;Dateventure&quot;.<p>I dunno - I suppose that it could possibly work a tad better if <i>the users themselves</i> would be able to create their own Dateventures, as in: &quot;Next weekend I want to go to the Improv Theatre seminar in XXX. I never had any acting training, but I think it could be fun and I always wanted to try it - any takers?&quot;
What happens if more than one answers? What if the other person will be a no show?.
