Posts
If you are using WordPress as a blog, then you will end up using posts for majority of your site’s content. Posts are content entries listed in reverse chronological order on your blog’s home page. Due to their reverse chronological order, your posts are meant to be timely. Older posts are archived based on month and year. As the post gets older, the deeper the user has to dig to find it. You have the option to organize your posts based on categories and tags.
Because WordPress posts are published with time and date in mind, they are syndicated through the RSS feeds. This allows your readers to be notified of the most recent post update via RSS feeds. Bloggers can use the RSS feeds to deliver email broadcasts through services like Aweber or MailChimp. You can create a daily and weekly newsletter for your audience to subscribe to. The very timely nature of posts make it extremely social. You can use one of the many social sharing plugins to allow your users to share your posts in social media networks like Twitter, Facebook, Google+, LinkedIn etc.
Posts encourage conversation. They have a built-in commenting feature that allows users to comment on a particular topic. You can go to your Settings » Discussion to turn off comments on older posts if you like.
Pages
Pages are meant to be static “one-off” type content such as your about page, privacy policy, legal disclaimers, etc. While the WordPress database stores the published date of the page, pages are timeless entities. For example, your about page is not suppose to expire. Sure you can go back and make updates to it, but chances are you will not have about page 2012, about page 2013 etc. Because there is no time and date tied to pages, they are not included in your RSS feeds by default. Pages are not meant to be social in most cases thus does not include social sharing buttons, or comments.
You don’t want users to comment on your contact page, or your legal disclaimers page. Just like you probably don’t want others to tweet your privacy policy page in most cases.
Unlike posts, pages are hierarchical by nature. For example, you can have a sub pages within a page.
WordPress by default comes with a feature that allows you create custom page templates using your theme. This allows developers to customize the look of each page when necessary. In most themes, post and pages look the same. But when you are using your page to create a landing page, or a gallery page, then this custom page templates feature comes in very handy.
Pages also have this archaic feature called Order which lets you customize the order of pages by assigning a number value to it. However this feature is extended by plugins like Simple Page Ordering that allows you to drag & drop the order of pages.
