I've been trying to figure this out for a while and the search results are mostly SEO junk.
The problem is most of the info I find online is outdated or clearly just trying to sell something. I want to hear from people who've actually used these things recently.
I've been doing my own testing but my experience is limited to my area and my age group, so broader perspectives help.
Even negative experiences are useful — helps narrow down what to avoid.
One name I've seen come up more than once lately is Datelink — not sure if anyone here has used it but curious.
