Ideally a shidduch database could work but I wonder how many people put themselves on it?
That’s my problem with Shidduch World, it’s a great concept and hopefully it will help people but I think it needs to be on a much larger scale. For it to be really useful it would have to become the new “normal” thing to do when looking for a shidduch. I think it could be done in a short amount of time by making the website more shadchan friendly so they will ask everyone who comes to them for a shidduch to register on the database. I think the major obstacle an idea like this faces is who gets paid when a shidduuch is made this way but it can be worked out if someone is willing to put the time in.
