I agree that a person needs to be careful with online dating (or any other kind, probably), and take time before you meet someone to get to know them well enough with writing, to think that you might enjoy being with them in person.
I belonged to a Christian website, and met my husband there almost 17 years ago. Neither one of us were really trying to find someone to marry, we just wanted someone to talk with and share our day to day lives with online emails.
He lived at one end of the country, and I lived on the other end, in North Idaho, (3 hour time difference) so I had to get up really early to “visit” with Bobby on Yahoo chat in the mornings, and I worked until late and then had to feed the horses and milk the goat before I was back inside the house, so he had to stay up late at night to visit with me then.
He was the director of a small Men’s Rescue Mission and couldn’t get away, so when I had a chance to go out and see him, I flew out to meet Bobby, and ended up staying, helping him with the homeless ministry, and then we got married.
I was in my late 50’s when we first started corresponding with each other, and I had talked with his pastor before I ever went out to North Carolina to meet him in person.
He is the best husband a person could ever have, and marrying Bobby was one of the best decisions I ever made.
So, I think that meeting someone online can work out, but you have to be careful and be sure that you know the person , and spend time writing with each other first.
If someone doesn’t want to take the time for long, earnest conversations with you online, then they probably are not going to be very good conversationalists after you meet them, either.
So, if communication is important , then be sure to find someone else who wants to communicate, too.
