Keep track of your online activity with Bit.ly Bundles
No sooner had Bit.ly Bundles emerged had Joshua Auerbach come up with a way to use them to keep a lifelog. For those of us who spend half our day online, it seems like the perfect way to round up all of our activity at the end of the day and decide what we want to save for posterity. Foursquare check-ins, Instagram snaps, an interesting article that was shared on Twitter, a blog post – anything that you feel affected your day can be added to the bundle.
If you can keep track of everything that happens in your day, you're streets ahead of me.
A lifelog may be the right form of writing journal for you, especially if you write and curate a lot of Web content.
