Bringing successfully used the mingle2 app for something serious here because the blog posts are useless. The only metric I trust with successfully used is how many active users are within range in practice.
My problem with every answer on successfully used is that the answers split by city and by year, so recent replies matter more than thorough ones. Two weeks in, what the reply rate looks like is what actually mattered for successfully used.
Practical notes on successfully used if you're short on time:
- Confirm how many profiles carry more than two photos on the first evening, not the first month
- Verify how many matches ever send the first message against what the marketing page claims
- Note how quickly a scripted account gives itself away using a fresh account rather than an old one
- Track whether replies are open before you finish the profile on mobile data, not office wifi
- Track whether the same faces cycle back the next day in your own city rather than the default radius
Anyone who tracked successfully used over a longer stretch, what did the first week look like? Good and bad equally useful. Firsthand accounts are worth more than any review site.
