The original meaning of microcontent is by usability adviser Jakob Nielsen, who in a 1998 article1 referred to Microcontent as short content, like headlines, which need to be immediately clear and inviting to a reader, and which still make sense when removed from their original context. For instance, on a search engine result page, the article headline may be displayed with only a short snippet but not the full article. "Microcontent should be an ultra-short abstract of its associated macrocontent," Nielsen said. He discourages traditional newspaper headline techniques, such as puns, teasers and other wordplay, which are more effective when the full story is already visible. He views the first word or two of each headline as extremely important to readers scanning a page.
The second meaning of the term has been defined by blogger Anil Dash2 in 2002:
In the years of the booming blogosphere the term became important and useful to describe the emerging new content structures that were enabled by new technologies (like trackbacks, pings and increasingly RSS), new types of CMS-software and -interfaces (like blogs and wikis), and not least by new socio-cultural practices (people creating, bringing into circulation and re-using/re-mixing microchunks of content).
Microcontent could be other forms of media like an image, audio, video, a URL (hyperlink), Metadata like author, title, etc., the subject line of an email, an item in an RSS feed. In 1998, Jakob Nielsen offered tips3 on how to write usable microcontent.
A sum-up of the discussion (with links to other definitions) and the implications for web-based learning can be found in the research paper "On Microcontent and Microlearning" (2006; link to online version).4
