I don�t think that people who use the internet to find partners are mad. I think to assume that you can find love on the internet is a touch sanguine, but that is not to say it can�t happen. The problem that many people find today is how to communicate with each other, and the internet and/or email facility is a good ground breaking tool for opening yourself up and exploring the ideas and emotions of another without being too involved from the outset. To some extent for the initial period of �getting to know� each other you have a form of self-protection in that you reduce the risk of being harmed psychologically or physically. You have the ability to cut off contact without fear, distress or any particular guilt.
The AB is a prime example of seeing how people connect in different ways and can find some level of commonality and bonding to certain aspects of their lives. In other factions you can see the lack of any cohesion between members, and in some rare cases, utter distaste. Natural selction and all that malarkey.
If an individual is prepared to go online and search for a soul mate then, providing they have an open mind and are able to protect their sensitivities and conduct themselves safely, then good luck to them.
