Hi! I think that the most important concept behind a vCard should not be the card itself, but portraying a (virtual) personal identity. In this way, when we represent only the persona shape instead of the card we make strong emphasis on this.

Second, and I paraphrase from the blog post, "using a circular container has its constraints, and trying to adapt a rectangular design in a circle is something problematic, specially by correct use of the available space and margins". This also was a driver towards the current circular shape.

Last, the at(@) symbol is crucial for the link between communication and virtuality, and also to separate this to the classic "user" shape.
