An interesting news item about relationships that start online suggesting they might be better than ones that start more conventionally. Unfortunately, I couldn’t find the detail of the study referred to in the news report.
I would say that it can work both ways – it can allow people to be more emotionally open but it also encourages (even more than usual) projection of positive characteristics onto the person you are corresponding with that may not actually be real, and because text can’t transmit tone of voice or body language it is dangerously prone to misunderstanding. So proceed… but with caution would be my advice.
