Then again, webtests seem to get more comments, according to my recent entries page.

Maybe it's not just that number of comments are inversely proportional to the length of the post - they're inversely proportional to the *amount of content* in the post, except for extreme cases (starting a meme obviously gets you lots of comments; being depressed tends to get you more comments).

If I had any invite codes left or any time, I might set up a new journal to test these theories. Maybe a statistical survey of my LJ-friends would do.

Meta-posts (posts about LJ, rather than about the poster's life) also seem to benefit from the extra-comment effect like posts mentioning comments.
