Shared hosting is a form of web hosting in which many web hosting customers share a single (virtual or physical) server.
The customers in a shared hosting environment are partitioned away form each other, so (when everything goes well), they have absolutely no access to each other’s files, and are ideally not even aware of each other.
Shared hosting allows for a high customer-to-hardware density, which makes it a very inexpensive way to run a website — shared hosting is the cheapest form of hosting, and relatively high-quality shared hosting plans can be had for less than $10/month (sometimes less than $5/month, with a good coupon).
The problem with shared hosting is that a limited pool of computer resources is being shared by a large number of customers. This can cause slow-downs and site outages if one or more sites on a shared hosting server gets a lot a of traffic.
To prevent this, shared hosting providers usually institute some kind of throttling — even on so-called “unlimited plans.” This usually kicks in if your traffic spikes, which makes shared hosting plans a terrible idea if you are trying to build a highly-scalable, well-trafficked website.
Because of its popularity, most shared hosting providers are well-equipped to handle a WordPress blog. Many even offer a simple one-click installation script, allowing you to get set up with a new WordPress site very quickly.

Usually, yes. The question is whether you want to.
If you are launching a more-or-less basic site which will have limited traffic — such as a personal blog, a homepage for a small offline business, or a website for local non-profit organization — then shared hosting is a great way to go. It will provide all the hosting power you need for up to several hundred visitors a day, for a reasonably low cost.
If you need a website that will work with larger traffic numbers — several thousand a day, especially highly engaged visitors on an interactive site (like a store or web app) — then shared hosting is going to be a terrible experience for you. You would be better off, in that case, with a VPS hosting plan.
