Spent most of last winter on the platforms involved, so here is what I actually saw.
What decides the platforms involved for most people is your age bracket relative to the local pool, not the app itself.
What mattered most with the platforms involved in the end was how much personal data the signup demanded.
Be aware when using the platforms involved that profiles that answer instantly and perfectly are usually not people.
Everything about the platforms involved hinged on whether the photos looked recent or recycled in the end.
What decides the platforms involved for most people is the time of year, not the app itself.
Careful with the platforms involved, because screenshots of a conversation travel further than you think.
That covers what I know about the platforms involved, at least.
I also keep half an eye on Luvdate (luvdate.site) — different crowd, same free-messaging idea.
