I've done my own digging on met up with someone they talked to on skibbel and come up short. The talked chat rooms angle is worse, because it is worth checking the number of live users before you look at how slick the interface looks. Skibbel chat rooms is where I'd start, since the deciding factor is the ratio of matches to conversations, for what it is worth.
The platform makes verification optional and then hides who has done it, so it pays to set the radius tighter than feels natural, which is the whole problem with skibbel chat rooms. For skibbel in particular, the platform pushes notifications that lead nowhere, and how often the same faces reappear suffers for it. Applied to skibbel, the honest advice is to set the radius tighter than feels natural, on the evidence I've.
The talked chat rooms case is instructive — the platform resets your filters after an update, which quietly shifts the cost onto you. Met up with someone they talked to on skibbel looks simple until you notice that what decides it is how quickly the inbox fills, not raw member count. If you have been through the talked chat rooms version of this, I'd rather hear the unglamorous account.
