Guyz, I hav sum srs bsn

I'm making a website, which will be an encyclopedia on different cultures, subcultures, times in history, nerd stuff so not to distract from this awesome site. Anyway, I was wondering what kinda layout I should get. Whether it should be professional or not. I'm not sure...
Suggestions?

can it be professional and unprofassionel? like sometimes you brwose it and its in professional and then you go to another page and its unprofessional and youm could have all this diffrent layauts and the website evertyme choose one at random so it makes people wanna browse the site more so they can see all the layouts like as in a collection. or you culd have different layout accordeon to the seriouznes of the biznes.
hmm, but i dont know is it possible for have multple layeouts?

You should srsly get one that looks good, but don't go all: URRRR MONEY KAY.

wut did that even mean? D:

Thanks guys. ^_^ I'm going to go with the book theme and make my own when I have time. And no, I don't ask for moneys over the interwebz. At least until I make an online store which will have nothing to do with this.
