My .com and 10 forwards via Godaddy?
 

As a cheapass I am looking to use ten diff .com forwards on one .com to all wordpress blogs. Good idea? Will it affect SEO etc?

bump........

If you can't afford the $8 for a domain, you have bigger problems than SEO.

Uh, no. You read it wrong. I have the ten domains already, I'm not asking about that, I am asking whether it's a bad idea to forward them to one hosting package.

I.e. 10 .coms all going to say porn.com/domain1 - /domain10.

Oh. Ok. Well, if you're pointing them all to the same content, yes, that's somewhat bad. At least put up a 301 redirect so your domains don't get penalized.

It'd still be better to setup different instances of WP, with a different theme, and share the same DB.

Yeah that's what I meant, diff instances. so ill be ok?

Not as good as having actual different data, or running a Markov chain on the output for 'slightly different' data, but different themes will help.
