Should I use wordpress or Squarespace?

[Manny]

On my website I would need people to be able to post their own pages, and not just comments. I do want comments though. I also want social media integrated, like Facebook, etc. I also want to be able to design easy, but I do want it to be nice looking. Also, how can I advertise my website after I finish?

I assume you are talking about WordPress.com? or WordPress.org they are different. But both can enable you to add people create their pages. It's called roles.

For wordpress.com : http://en.support.wordpress.com/user-roles/

For wordpress.org: http://codex.wordpress.org/Roles_and_Capabilities

WordPress or Squarespace: I'd go for WordPress, there are endless flexibility, like social media plugin, tons of free or premium templates. While squarespace is also good, it doesn't have a lot of flexibility and popularity as wordpress.

To advertise your blog, called, SEO-ing it.
