I suppose the one thing to do is make sure you read the person's profile and find something to comment on
The fact that you realize this and put effort into your communications probably makes you a good communicator online and thus women enjoy conversing with you.
95% of the men I converse with on here do NOT know how to and thus I feel like I am doing all the work, so the convo generally fizzles.... Hence the reason most men prefer to meet in person sooner rather than later.
I can expect what I CAN offer. :D
Internet dating does work - I know of several couples and 4 are engaged - 3 met through local POF events.
So when someone whines to me that they can't find anyone online and they have not exhausted their resources nor do they know how to communicate properly - I really have nothing to say to them.....
