I think this is silly honestly. Girls already get bombarded with messages and are more likely going to be looking at an inbox of guys who already showed interest so guys promoting themselves for 10 minutes aren't going to get looked at anyway since the girls will be checking their inboxes.
The whole online dating idea is bad for men. As a man, you're competing against all the confident guys and all the shy guys who use it instead of approaching women in real life.
And you've got to wonder at what kind of woman would end up in the position of having to create an online profile. Most likely, she has a bad personality that drives men away as soon as they get to know her, or she has super high standards that likely won''t be satisfied by anyone, or she has no interest in online dating and actually simply wants to boost her ego by getting lots of messages.
