I don’t think there’s anything wrong with it, in this day and age especially.
There’s still a lot of people who strongly disagree with it. Each to their own, but it’s now advertised on tv, recommending that people give online dating sites a try, and for those who say that you never know who you’re meeting, in my opinion, the same still applies wherever you meet, whether online or in ‘real life’ – so, yes, as in all cases have your wits about you, but do whatever you feel is best, don’t let anyone tell you where and when you can and can’t meet someone and live your life how YOU want to live it.
