Figures I decide to join Instagram the day Facebook buys it. Of course, it was the publicity from the Facebook sale that prompted me to finally try it after hearing so many raves and seeing all those sepia-toned photos on Facebook.
I would never place any bets on a company's goodwill or its business sense, but I suspect Instagram will do just fine under Facebook. (Talk about predictions sure to go wrong.) More and more people will learn about it, and it's going to make people want to share more and more photos on Facebook. That's reason enough for Facebook to want to see it prosper.
