A Quick Way to Unsubscribe from Feeds in Google Reader
You can unsubscribe from feeds in Google Reader via the Feed Management page (see image below), but it's not the most efficient way of managing the feeds.
Using this method to unsubscribe can be tedious and time-consuming, because you have to leave the page you're on and then scroll down to find the feed you want to unsubscribe from.
Instead, to unsubscribe from feeds in Google Reader:
1. Assuming you're reading feeds from the All Items view, where all feeds are aggregated and sorted only by date, click the post title to expand the view.
2. Click the name of the feed as it appears next to the word "from."
3. Click the Feed settings button and select Unsubscribe.
