I think it works fine as it is for a community site - the stuff relating to dating / looking for / matches etc can all be disabled. The only thing that is not easily disabled is the 'kisses' feature (Greetings) but this can easily be renamed to be more suitable (beer / kudos / whatever).

From a software perspective I would disagree that a social net script can more easily be modded to be a dating script than the other way around. IMO the dating script has more complex features - such as couples see more profiles and matchmaking - it is far easier to already have these features integrated and then simply disable them. To add them in after-wards is a lot of work.
