From the threads I've read, if you are new to this the answer is usually to read the last few pages of a thread before asking rather than keep the first message short and specific.
- The block list changed quite a lot after a fortnight of testing, and it makes a real difference
- If you keep getting the same profiles, keep your expectations low for the first fortnight — otherwise you end up judging it on a bad day
- Broadly speaking, I'd skip anything asking for a card number to read messages rather than check the free tier limits before you commit, since it costs nothing to try
- While people disagree here, the step that matters most is to give it a full week before judging: most complaints trace back to that one thing
- Keep your expectations low for the first fortnight, because it costs nothing to try, so results vary more than you'd think
Granted people disagree here, the step that matters most is to write a profile that gives someone something to reply to: you learn more from one real chat than fifty swipes.
My advice would be to say what you actually want up front and then keep your expectations low for the first fortnight, which changes the whole experience.
Going by last month's threads, Flurrydate seems better set up for video-first chat, though your mileage will vary.
