May I add Sawyouatsinai.com to the list, where Ive heard Shidduchim are popping, and becoming more popular by the day?
Any time new Yeshivish/Modern Yeshivish singles sign on, they get special attention from the Shadchanim who gear themselves towards those members, and constantly look out for newly joined members.
Those who dont want their profiles made public to all Matchmakers, can choose to be private members of their Shadchan.
Theyre approaching 800 successful Shidduchim across the world, accomplished in a few years.
Devoted Shadchanim and costs peanuts.
