One of my go-to places for learning Blogger tips, tricks, and hacks is Blogger Buster. For the last year or so it was fairly dormant. In the last couple of weeks, it has come back to life with a bunch of new tips and tutorials. It's also a good place to find custom templates to use with your Blogger blog.
Applications for Education
If you're having students use Blogger to maintain their own blogs or digital portfolios, you may have some students who want to customize the look of their blogs to make them stand-out from the crowd. For those students, Blogger Buster could be a great place for them to find hacks to customize their blogs in their own unique style. In trying these hacks your students will also learn a bit about HTML and CSS.
