There is a new Twitter-frontpages template available in the release tests and svn.
Create the domain twitter.com
Set twitter.com to use Twitter-frontpages in defaultconfig and set a suitable domain limit.
Download the order template. Edit it to include some suitable keywords, e.g. from today's news, and reupload it.
Make a selective harvest of twitter.com.
Look in the crawl logs and/or browse with viewerproxy. The results should make sense given the search criteria.

See NARK-142 for more detail in Danish (I'm afraid).
