From Social Patterns
Users like to be able to collect and display media objects (such as videos, images, and even slideshows) as well as badges and applications on their profiles, blogs, and activity streams.
Embedding works best when displaying media or other objects that can be distributed freely.
Generate an embed code. An embed code is a snippet of markup that a user can copy and paste directly into a blog entry template, MySpace page, or other social space for sharing that the user controls.
You may need to supply unique variations on the code to support variant hosting environments or to make the process simpler. Slideshare, for example, offers a generic embed code for most situations and a different code for embedding slideshows in WordPress blogs.
Optionally, give your users the option of customizing the size, color palette, and presentation of the embedded object (both Slideshare and YouTube, for example, enable the user to opt out of the display of related objects - slideshows and videos respectively).
When possible, gather statistics about number of times an object has been embedded, where, and how often it's been viewed or accessed through embeds.
Users like to share and display content. The more easy you make it for them to do so, the more likely they will. Embedding also has strong potential for organic spread, as it enables rapid duplication and redistribution. It is widely thought that YouTube obtained much of its early phenomenal growth from the fact that its videos could be embedded easily on MySpace pages.
