It is actually a pretty lonely existence. Plenty of casual chats, followed by endless email exchanges, attempts to set up a "meet", and then radio silence.
I get that people are all looking for different things, but I can never understand why they seem interested in leading people on if they have no intention of following through.
I can understand how this might sound like sour grapes, but it would go a long way if people were just up front about their intentions and interests.
