depends what you are looking for.. wordpress is a blogging platform, so if you are after a blog, with some minor customizations for front pages, it might fit your needs, if you need a cms, i wont recommend it.
If you need a cms try joomla. You can find lots of extensions/plugins for it and I thought it was quite user friendly.
I would recommend Wordpress for most things, it's got alot of extensions and themes and it's all available for free. You could take a look at http://modxcms.com/ for CMS purposes.
I second the recommendation for Joomla. It has a huge community built around it with 1000's of extension. Check out extensions.joomla.org to view what you can add onto your site. Many of them are free too.
