Okay so I'm gonna cherrypick a set of your comments and decontextualize 'em to serve my point. God bless the remix culture.
fgk, on why people don't take lessons from those who offer them:
i think a big part of why we don’t adopt [lesson plans] from others is because we don’t see it happening. when you watch a class, you can tell when something succeeds, and figure out how to incorporate that into your own teaching.
druin, on the frustrations of sharing lesson plans with others:
I think for many people the idea of sharing is lop-sided. I don’t mind sharing ideas with others, but it frustrates me when I’m the only one sharing.
sarah, assessing my lesson offerings:
The power of your narratives is the piece that keeps me hoping that something turns up in your [lessons] tab. It’s that reality check of what works. It’s hearing your voice, getting hints of your personality, helping me mentally test what I can pull off, and what, like rap music, would be obvious that I’m faking. That voice is what every lesson plan needs. [emphasis added]
So my advice is this: you have to make stories out of your lesson plans, collapsing resources into anecdotes. It's easy to blog stories. They're cathartic and satisfying where resource posts feel expensive. Plus people are more inclined to read stories than rubrics.
Talk about the questions you asked, the responses they gave. Share pictures or screenshots when possible. Post stories, not plans, and then attach handouts or link sources at the end. I can't help you with the time cost but if you're convinced you should share your resources, I promise that this is the way to make it fun for you.
Moreover, I promise that as you start receiving feedback on your stories — positive & negative — you'll start looking for more stories to tell. Constantly. The pipe that carries interesting things from your eyes to your students' and then to your readers' will grow wider. It'll move faster. If you start this in earnest, I pomise you won't be able to turn it off.
