voice - yes I think people are too shy, in some cases. Generally I get winked at by women who are either scammers - obviously so, or I just don't fancy them. Too old, too far, too unattractive, too obviously mad.
I've received a few emails out of the blue from people I liked, and have had a couple of dates from that, but generally OD is very old fashioned. The men do the 'winking' and hope, usually in vain, that their wink is soooo much better than the other winks the woman in question is getting that she'll be intrigued enough to look at his profile and either wink back or message him first.
Generally, although not always, women wait to receive a decent mail from someone she likes. The different sites make people act differently, however, and the amount of dross on POF makes some women hide their profile and just approach men they like - otherwise they're drowning in the sparkling wit of 'hey, howz u? U look purdy'
Winks and smiles and favourites have their place. I don't bother winking, if I like someone I mail them. And sometimes they respond. I use 'favourites' on Match to store the profile of someone I've seen when I really didn't have the time to send an email, or I'm already mailing 2 or 3 women, some of which may lead to dates and really don't want to try and have 4 or 5 conversations going on simultaneously. Then when all of those 2 or 3 crash and burn, I can mail the favourites. I don't expect them to respond to that though, they probably have enough guys favoriting, winking and 'hey babe'-ing them.
How are you doing on the OD scene by the way, voice? Active?
