Add Feeds to Google Reader in Internet Explorer 7:Unlike Firefox, Internet Explorer 7 doesn't let you subscribe to a feed using your favorite feed reader. You can only use the feed reader included in IE7, which is not that good. That's probably the reason why
70% of Google Reader's traffic comes from Firefox users.
Google Toolbar 5 took the liberty to add options for subscribing to feeds in iGoogle and Google Reader. So the next time you want to add a feed in Google Reader, you can just click on the orange button from Internet Explorer and select one of the two options added by Google Toolbar.
