We need everybody. Why would we reduce the pool of Shadchanim, whether the “heimish” neighbor or professional with a system, especially when many complain they’re not getting suggestions?
And how many friends of a friend would do the legwork for say a Transatlantic shidduch? Or for the older guy/girl that’s very sensitive and may stop talking to the so called Shadchan if he/she becomes offended? Many times people think of a Shidduch and refer it to someone more “professional” because they can’t be bothered or don’t fee competent. And there are many shades of grey between so called professionals and say the teacher that dabbles in Shidduchim.
