I've been online dating since I got out of highschool 5years ago. Met the guy I lived with for 2years while going to college on an online site I don't remember. That ended very badly and probably wasn't a smart idea. Then last year about this time I decided since I hadn't met anyone since him I'd try it again. I tried match.com, chemistry.com, farmersonly.com, eharmony.com and most of those just plain suck in my experience. The rest cost too much money.
Then I settled on plentyoffish.com for awhile which is free. Got tons of responses despite not putting up a pic. Most were bad responses and got deleted or put on block in less than 5mins. Some were way above my age range and I don't really want to know why they were messaging someone half their age. I did get a few good responses. Talked on aim, talked to a few on the phone including one every day for a few weeks. Didn't work out. There were things like his smoking when I can't stand cigarette smoke and it makes me cough all night that led to me not wanting to meet him. Didn't find anyone I was willing to meet so I gave up for a few months when I got an email saying I had a message on an okcupid account I made 4years ago just to take the tests. The guy just wanted to know why I hadn't filled out anything and suggested I should try it. I told him I just set it up to take tests but it got me thinking.
So I filled out my profile, took tests, match questions, and my inbox filled with messages. Surprisingly they were good messages. I've ignored maybe 2 out of 10 guys that messaged me on okcupid versus answering maybe 2 out of 20 on plentyoffish. I've met people off okcupid and I've seriously dated some. I went out with someone last week who was a really nice guy and some girl will enjoy a nice safe relationship with him but I'm not quite interested in settling down like that yet. I've got another guy I've been talking to since before christmas and I'm meeting probably next week. Then I usually end up talking to 1 random guy a day that isn't bad but I'm not interested in and I have 2 stalking targets right now. Everyone who views your profile is called a stalker and you can view them so I pick 1 or 2 of those people that I match well with, rate them high on the match system so it shows up in their inbox, and then stalk them by opening their profile daily until they either message me, I get bored, I find a new target, or I decide I really do want to talk to them and message them first.
It does keep me entertained and I might meet 1 guy a month outside of the internet that is dating potential so online really works well for me. I have never had a situation go really bad aside from just not getting along with the person. I've never agreed to meet in person or given out too much information unless things felt right and until I knew a bit more about the person. I've managed to completely weed out anyone that wasn't safe to meet in person and I take precautions when I do. Generally first dates are simple things in public places that I am familiar with or with a group of my friends or my sister and her friends. If you exercise a little extra caution weeding out the bad responses you get and making sure you meet somewhere safer then it's no more dangerous than going out with someone you just met in person.
My brother uses singleparent.com. He doesn't have any children, was married for 12 yrs and they lost a child then shortly thereafter divorced. He loves children. He's met a few girls, flew to PA to spend the weekend with one and now has another coming to visit him. I don't think he'll ever remarry but he's always looking for companionship.
Edit to Add: I guess I should say he's met a few women, as he's 46 yrs young
Well when I was in high school, and my parents had AOL. I would recieve and send instant messages to/from girls my age in my town. We would chat then call each other, then after awhile we would decide to meetup to hangout.
It was always the same situation ! She was either a heavy druggie, sexually promiscuous, or flatout crazy. I learned you cannot go by a AOL profile and what a complete stranger tells you over the phone.
Once I turned 21 I found out its the same situation at the bar scene.
Luckily I found the love of my life at Buffalo Wild Wings in the middle of the day when its really just a restaurant.
