http://slashdot.org/ is a community web site where contributors provide pointers to articles elsewhere on the internet, as well as opinions, flames, etc. on those articles.  There are also frequently reviews of books, software, and general questions of discussion.

The term ''slashdot'' is sometimes used as a verb, as in "my site was slashdotted" - a term indicating
that there were so many visited that one's web site was unable to cope (or nearly so).
