There are two different WordPress sites, but from your question I'm assuming you mean wordpress.com.
Like pretty much all hosted blogging sites, ok at best. The 90's are long gone, and I honestly can't figure out why people still use sub-domain sites for anything other than back-links. Especially with how cheap it is to buy hosting and a domain.
If you meant wordpress.org, it's great. It gives people the opportunity to have a fully functioning, good looking site with no coding experience. I think anyone who has a website should know at least a little coding, but then again I also think if you can't change the oil you shouldn't be allowed to drive a car so my opinion on that doesn't mean much.
