Reply Reach
This morning Jesse Gardner tweeted:
When I’m writing an @reply, it would be cool to know how many of my friends would be seeing it in their feeds.
Which reminded me of Eric Meyer’s Followerlap. So for my morning mental calisthenics I whipped up a simple JavaScript bookmark that allows you to check your reply reach before hitting the Tweet button.
Just drag this Reply Reach link to your bookmarks bar and give it a click the next time you hit that reply link.
