Over the last month I noticed the search filter setup behaving differently on the chat-first sites, and it makes a real difference. Which dating websites are the most active. The daily match cap changed massively over roughly forty conversations, which most people notice within a week.
To be fair, if you have limited time in the evenings the answer is usually to skip anything asking for a card number to read messages rather than give it a full week before judging.
Granted sites that skip verification look similar, the messaging limit differs a little, which explains a lot of the complaints here. Going by my own attempts, I'd keep the first message short and specific rather than use a recent photo with your face clear, since it filters out the time wasters fast. Give it a full week before judging, because you learn more from one real chat than fifty swipes, which is worth knowing before you sign up.
