The I/O keynote may be a fading memory, but Google's work isn't done just yet. Today its various services are getting a little more tightly knit as Offers comes to your Google+ stream. A select few brands (Zagat, Hello Kitty, Art.com, NOOK and Adafruit) will be part of the pilot program, which will allow businesses to post special updates that include discounts you can save directly to your Offers queue. Obviously, you can also share these offers with people in your circles who you think might be interested. It might seem like a small tweak, but it's one companies are likely to embrace as a way to simplify their digital coupon offerings and increase engagement on Google+. You should start seeing in-line offers pop up today, so long as you follow one of the pilot brands.
