It might be worthwhile for you to edit your mind dumps given that the payoff will be multiplicative across your readership. Let's say you spend 20 minutes editing your mind dump and compress it to 50% of its original size. Maybe originally it took 10 minutes to read and now it takes 5. If your post has 100 readers over its lifetime (quite plausible to me given the number of lurkers on Less Wrong, the way people will stop voting once a post reaches its "just" score, and the high number of comments many posts get), then we are 480 minutes ahead of where we were. (Incentivizing people to do things like this seems like a positive side effect of voting.)
