This is part of a series of posts (and a project-in-progress),
compiled as a glossary of terms and phrases used in blogging and social
media, that will continually be added to and modified.

HTML: The acronym for HyperText Markup Language. The coding language used to create and link together documents and files on the World Wide Web. The code is embedded in and around text and multimedia files in order to define layout, font, colors, and graphics.
Haloscan: A free, easy to use commenting, ratings and trackback service for weblogs and websites, allowing visitors to leave instant feedback. Popular on Blogger sites.
Hat Tip: A hat tip is a public acknowledgment to someone (or a website) for bringing something to the blogger’s attention. Also known as H/T (H/T for this definition: Blogossary)
Hits: A measurement used in Web analytics, a "hit" is often defined as any request for a file from a Web server. In one web page, there could be several files embedded in it. If on one page you have four images, two JavaScript items and you use an auxiliary CSS file — you’d have eight hits on one page.
Hyperlink: A navigational reference to another document or page on the World Wide Web.
If you’ve suggestions, additions or modifications, add ‘em in a comment. Together we’re smarter.
