Why is a server side aggregator better than a desktop aggregator?
Desktop aggregators are great. They sit there all day, pinging away at sites, and as soon as they notice something new, they pop up little windows on your desktop, and let you read items. But what about when you go home from work? Or what about when you are on a trip? You get totally out of sync, and don’t know what you’ve read and haven’t read. You are enraged.
Check out Feed on Feeds… you just need PHP and SQL running and you can have your own agggretor running within a few minutes. I easily pointed to my existing OPML file from the blogstreet info aggregator and was using my existing subscriptions with little effort.
