Everything about Blogs and Blogging

Podcasting

Podcasting is the distribution of audio or video files, such as radio programs or music videos, over the Internet using either RSS or Atom syndication for listening on mobile devices and personal computers. The term podcast, like "radio", can mean both the content and the method of delivery. Podcasters' websites also may offer direct download of their files, but the subscription feed of automatically delivered new content is what distinguishes a podcast from a simple download or real-time streaming (see below). Usually, the podcast features one type of "show" with new episodes either sporadically or at planned intervals such as daily, weekly, etc. In addition to this, there are podcast networks that feature multiple shows on the same feed.

	Podcasting's essence is about creating content (audio or video) for an audience that wants to listen when they want, where they want, and how they want.

Video Blog (Vlog)

A vlog or video blog is a blog (short for weblog) which uses video as the primary content; the video is linked to within a videoblog post and usually accompanied by supporting text, image, and additional metadata to provide context.

Blogs often take advantage of RSS or Atom for syndication to other web sites and aggregator software (feed readers). With development of RSS enclosures, which provide the ability to attach media files to a feed item/blog post, or the use of the Atom format (which supports rich media content by design) it is possible to bypass the mainstream intermediaries and openly distribute media to the masses via the Internet. Vlogs typically take advantage of this technological development, just as audioblogs have in recent years via the podcast boom.

	As of 2006, videoblogging is rising in popularity, especially since the release of the new Apple Video iPod and the availability of iTunes Store's video content. iTunes uses the term video podcast to describe a video blog.

One of the potential problems with Vlogs is the current inability of search engines to create rich metadata or "search engine" data from the stream. For Vlogs to be fully embraced as part of web culture, some indexing solution will need to emerge.

Photoblog

A photoblog is also a form of a blog, differentiated by the predominant use or focus on the author's photographs rather than text. Some blogs also contain pictures; some photoblogs also contain text. When is a blog a photoblog? When the images are not just used to illustrate the text, but are the main subject.

The use of personal image/photograph galleries have been around for many years, but it was with the emergence of blogging, and the systems that enabled blogging, that people found themselves able to publish images to their website in a chronological order - thus adding a fresh and dynamic approach, as opposed to the static gallery.
