Pros
Because of its size, there always seem to be job opportunities. WUBS provides decent benefits, including a generous PTO package. They pay lip-service to many of the qualities one might look for in a company (though it's harder to say if they deliver). If you work in sales then WUBS may be able to provide a great opportunity because it's difficult to offshore these positions and they need them all over the country to maintain and build a customer base.
Cons
They don't seem to have a consistent direction. They're always in the process of building new products or re-branding, but before reaching their stated goals, the direction changes. Despite the size of the company, it's difficult to move-up internally, however lateral movement is generally an option. They seem to do most of their management hiring externally, and are in the process of offshoring much of their operations and technical support.
