I'm thinking of using a newsfeed on one of my sites and I'm wondering if you guys use them and what you think of em. Do they bring visitors more frequently? Do they compromise security?
The one I'm thinking about is a php RSS viewer, it looks pretty easy to install, has editable templates for customization, and an admin interface. Most importantly, it's GPU licensed so it's free: http://zvonnews.sourceforge.net/zfeeder.php#tips
I'm assuming these have no effect on search engine ranking because the script is called using a single line in the page, so the content isn't spiderable.
