I use Google Reader to keep up to date with all the websites I'm interested in. I don't have to trawl the web or visit my favourite websites for news and information unnessecialry. I subscribe to the website or topic I'm interested in and it all gets delivered to Google Reader. If a story interests me I can visit the website it came from to read the whole thing. Within Google Reader I can also share items with my friends easily and star (save) items for later. Because Google Reader is a web-based browser application, I can pick it up from any computer or mobile device with an internet connection.
According to Google Reader's stats, this is what I digested in Jan 2009:
From your 168 subscriptions, over the last 30 days you read 40,659 items, starred 54 items, shared 212 items, and emailed 21 items.
