I think you should definitely give it a go, you have nothing to lose!
I actually met my bf online and we have now been dating almost a year and a half! And I love him so much and Im so happy with him! I was hesitant at first but you have nothing to lose.
My only piece of advice, talk to them a bit before you meet up so you know a bit about them. I had ppl wanting to meet up asap but I didnt want to rush it, especially being a girl and being vulnerable. My bf and I talked on msn for ages (like a week and a half but for like 4+hrs a night! Lol) before meeting up so it wasnt so daunting.
Give it a go! Its fun if nothing else!
