What Makes A Quality Free Site?

[Tekster]

Link List owners, and reviewers what makes a quality free site? Is it the sales text, the graphics, the look, what do you consider a quality free site?

Second; how do you write good sales text, I mean what inspires you? Do you like the hardcore sales text or the softer side? Examples and ideas are more that welcome. Any good web sites for learning to write sales text?
(I think this would help quite a few people besides myself)

Any good tips for making a good free site? Besides the obvious like read and obey the rules, picture quality etc.
