If you go to Slashdot at all, you have probably noticed that the Slashdot software automatically puts the domain of a link after the link, for example:
blah blah blah at my home page [www.romsteady.net] blah blah blah
Well, today, I noticed a few posts that are using redirect scripts used by popular domains, such as msn.com and penny-arcade.com to make it seem like the links are going one place, when in actuality, they're going another.
If you are a Slashdot visitor, remember to look in your status bar to see where the link really goes. You can practice using this Slashdot weenie's post.
