If you choose to take it in your hands, to manage it yourself, you gain more, a good circumstance for self reflection you won't meet too often.

If you see it as a service, sure, if you are very successful and don't have time that someone literally has to manage your dating, then more to you I guess...

On the other hand, for people who are bad and incorrigible at self reflection, a serious matchmaker who knows you well can do a good job in finding you a suitable partner. But somehow I distrust this kind of online service, and that's me. "Local" matchmaking seems to be working in smaller communities.
