Making Your Website Friendly for Visitors

I browse a lot of websites and I especially enjoy browsing sites that are friendly for visitors. There are a few characteristics of such websites. First of all, internet users appreciate when a website is easy to navigate. In case of WordPress blogs this is not an issue as they are designed from scratch to be very easy to navigate. You can browse posts by categories or by the date of posting. You clearly know where to find new content and that is very important in my opinion. There are many websites out there where it is hard to say which page got updated at which time. How would you know if the content you are browsing is not outdated?
