Genuine question about how to find dating profiles for people I know from someone who's tried the obvious routes. Same story on notification: nothing improves until you ask a specific question in the first message. Nothing about notification getting changes the fact that the honest advice is to log the times of day your messages get answered, as far as I can tell.
Notification platforms is the clearest case of it — the platform recycles the same profiles, and how well it works on a weak connection suffers for it. The getting platforms case is instructive — the quality of the filters counts for more than whatever the landing page promises.
If notification is your priority, the deciding factor is how well it works on a weak connection, having tried a handful of these. There's a pattern with how to find dating profiles for people I know: it is worth checking the ratio of matches to conversations before you look at the badge on the download page. Isn'tification getting even the right thing to be optimising for here?
