The church website I maintain has 50+ short content items about our denomination's history that are randomly rotated with the Joomla core module mod_newsflash, as "teasers" to catch a newcomer's attention. The first paragraph is unique to each item, but the second is common to them all, containing a brief description of the denomination and a link to its official website.

Rather than doing tedious copy / paste operations for this second paragraph, I've simply entered the text and link HTML into the MosSnippet back-end and include it in each teaser with a single plugin reference. Simpe, fast and easy to edit if need be.

Also, at the bottom of all the main-body content items, I have a "return to top of page" image link included with {snippet top}. Again, nice and easy.

Pro - You can refer to any one of 15 snippets via the snippet number e.g. {snippet 1} or give each snippet an easy-to-remember name and refer to it by that name e.g. {snippet top} yet the numeric reference will still work, too.

Con - As of 1.00 beta, back-end does not prevent duplicate snippet names
