I think everyone is looking for depth in any relationship, especially BDSM where the choice of partner you make can have a more serious impact on safety and well being. It goes both ways... I am usually more suspicious of a Domme who comes across as 'uberDomme' than one who displays some level of humanity in her interactions - sense of humour, vulnerabilities and so on. The former may have something to hide (in some cases what they have to hide is that they are not really a Domme at all) whereas the latter is more likely to be a real person with real needs.

So, both sides need to be aware of how they come across to others. Especially in things like forum posts and e-mails where emotional responses are harder to convey.
