i wouldn’t change it; for those who feel comfortable with the current set-up, bruchim tihiyem. I’d add to it by going back to basics.
My parents met at a single’s weekend in the Pine View Hotel put on by the Zeirie Agudas Yisroel in the ’30’s. There were at the time no other ways for frum singles to meet. Now, B”H, for many, there are. However, for singles over thirty, the ability for meeting the right zivug grows very difficult. I think it’s time we realized the need for more innovative approaches, including setting up carefully screened (and shadchan-attended) weekends or singles events under the auspices of recognized rabbonim or frum organizations (as Rabbi David Cohen did, once, many years ago).
