“We struggle every day as authors to get the word out about what we do. It’s important to be firing on all cylinders. The agreement between Google and Twitter might help us in that endeavor. So, if you aren’t active on Twitter, maybe now is the time to reconsider. It will take a few months before the effect is noticed on Google, as the best estimate of the functionality taking place is sometime in the first half of the year. Happy tweeting!”
