Interestingly, Blogger mentioned their upcoming 10-year mark back on June 18th, and again, this last week, on August 17th, when they said: "we wanted to give you some presents to commemorate this milestone and thank you for letting us be part of your story. Over the next several weeks we will be releasing a number of new features..."
In a given day, I get the opportunity to publish to WordPress, TypePad and Blogger, assuming I update blogs here, at work, or make an addition to my mom's site - still going strong since 2004. Each has its unique differences and challenges. I know that by sticking with Blogger, I've gained some benefits with ease of publishing, and some downsides as advanced widgets make their way to other platforms first. But if I thought the platform were standing still, I'd have jumped, and I know it's not. I'm looking forward to the new releases, as they happen, and congratulate the team on their hitting the big 1-0. Expect more news soon.
