I think its very useful when searching for something that’s untenable within your own real environment, being at work all day, having to work weekends, spending time with kids etc. can preclude you from actively seeking a new partner.
Ok so you can try a chat up someone at the local supermarket but in my experience the ones I fancy are always in a relationship lol and I am not a pub/club person,
Having said all that, when in a relationship, the internet should only be used for finding info on cinema times etc not for chatting to others. The art of longevity in a relationship is conversation. WITH EACH OTHER !!!
