'you' or 'my' in domain names

Which one is better from a marketing perspective.

[Rosko]

From a marketing point of view which is better and more appealing? ..for branding and repeat visitors:

- yourwidget.net
- mywidget.net

[peewhy]

I would think it depends on whether uou are buying or selling.

'my' is possessive. 'My photos' - 'my widgets'.

My vote goes on 'your'.
