Pay attention to usage comfort. It will simplify navigation on your site and will not decrease its aesthetic value.

"Usability" became indissoluble with the word "Internet". You will not convince an opponent, that your site costs something, not mentioning about the comfort of usage. Qualitative design should also be convenient, but the last point is the most important in site development. Both beginner and professional should know how provide convenient usage of the site he creates.

Key part here is acted by carefully thought out navigation. If it is absent, the design of the site is unsuccessful – the user will not even want to look it through.  How long will you drive a car where lever of transmissions is on the back seat, and a helm turns only in one side?
