on quality: it takes me about 40 minutes to write a summary of something that I've already read and understood. That's about the level of detail and quality I need, for my own learning purposes. It might even be informative to other people. Summarizing is a modest goal, I think, and it shouldn't take anything like "genius."

Quality matters if you have a community that's interested in your work; you'll get more "nice job" comments if it IS a nice job.
