Every day, we compile a list with the most interesting tech stories published over the last 24 hours.

Today was one of the busiest news days in quite a while. Google launched a massive update for Google+, for example, and Facebook launched some nifty updates to its newsfeed. At the same time, Instagram launched version 2.0 of its popular photo-sharing app, Amazon quietly started its Kindle library lending program and the U.S government started its investigation into online poker site “Full Tilt.”

To read these stories (which we curate with the help of Pearltress), just click on any headline in the embed below that sounds interesting. An overlay will then pop up and allow you to read the story and navigate to all the other ones as well.
