Hi
Personally, i was of the 'meet up quickly' school of thought. Having done it for around two years on and off, I quickly found the email stage a bit repetitive and boring, and was always a little wary of sharing all my small talk before the date!
I found that it can work both ways in that people who you think you will really click with turn out to be really disappointing, and people who I was a little more indifferent to over email were much more engaging in real life. So It did reinforce my feeling that the email stage was (for me) a bit pointless.
My tactic was to email for no more than a week to see if they seemed interesting and then suggest a drink or a coffee.
This also means that you don't have time to get too anxious about the date, and you haven't invested too much time and energy in a person who you will never see again!
My last tuppence worth is simply: have faith!! I went on loads of dates, some successful, most not(!) but actually always had at least a nice conversation and beverage! There were times i was disillusioned but...
After all that I met my lovely current partner, and we are very happy!
