Hmm.. an automated concept might be more useful.
If I had time, I'd code it. An "articlebot", like Sitepoint.com has for their forums when new articles are added.
Although, your method of fetching articles is somewhat broad and unclear, if you plan if you intend to grab the content from a news article by a user-submitted URL.
A better idea is to read a news feed XML from an XML parser. Not sure if you're familar with PHP's PEAR, but there is a great package by Stephan Schmidt known as
XML_Serializer that easily parses XML data to arrays. Another of course is
XML_Parser.
Then you just find
XML news feeds, e.g.
http://www.securityfocus.com/rss/news.xml
http://www.computerworld.com/news/xml/50/0,5009,,00.xml
http://rss.news.yahoo.com/rss/tech
And have the "ArticleBot" display the URL and description inside the post.
Something to think about.
This would be a most useful hack though.
