Chrome: Now that Google+ is open to the world, you may be interested in pruning your circles to make sure you're only following people who are actually communicating with you. Uncircle+ is a new Google Chrome extension that will look over your circles, show you who is inactive, and remove selected users if you want to make changes.At the moment, Google allows you to have 5000 in your circles. If you're particularly talkative or like to add a lot of people to your circles, Uncircle+ can help you remove inactive users so you have more room to add people you'll actually engage with, or who are actually using the service. The extension isn't perfect though: it removes users you select from all of your circles, not just selected ones, and it doesn't save searches yet, but the developer is planning additional features in future releases. It's available now and works anywhere Chrome does.
