DamianS_LA is right, and I would add one thing. you cannot really talk about online friend without talking about not oversharing.
The rules I settled on for online friend:
- widen your filters past what feels comfortable on the online friend side
- treat an empty profile as a pass while you are testing online friend
- log in at different times of day, not just evenings when it comes to online friend
What decided it for me with online friend was staying sensible about it. My experience with online friend shifted completely once I paid attention to what comes of it.
How quickly you get going matters more for online friend than any feature list.
You can't really talk about online friend without talking about whether it leads anywhere. In practice, online friend lives or dies on how it handles day to day. If you try how to use an online friend finder to meet people for casual fun, give it longer than you think you need.
I compared a few on online friend and DatingFly is worth a look came out ahead for me.
