People use Facebook to find and keep up to date with friends. The site is content-driven; users publish their own photos, comments, videos, etc and other users read them. Popular with students as it can be used to arrange events and has a built-in invitation and RSVP system. Members can form groups around interests, clubs and societies. Accessibility information can be found at AFB's blog and the CAPTCHA is offered as an audio sign in. Facebook Accessibility pages are also very helpful. m.facebook.com is an accessible option, although it is designed for the mobile phone.
