sure... the problem comes when your site uses iframes... if you don't specify this target (or something equivalent) you will have the new page open inside your nested frame, and not in the whole page... for example in my homepage I have one iframe in the center (it's the text area) all the rest is static... and if I don't specify a target like this in the link URL every link that points outside of my site (for example
www.google.com) would open in the iframe, which would be stupid...
I did notice that it made the browser open a new window indeed, but that was not the effect I was looking for, at least as far as my site is concerned...
