Shorter posts definitely sound like a good idea!! :) Not that I don't like your longer posts, but anything that takes less time out of your already very busy day sounds good to me :)
Also, I think videos could be fun. Did I imagine it or did you say once that you're not too keen on doing that? Might be a good way to get over that dislike :)

And at least one duckface a day, man :) I don't know how you've kept this blog running so long without one!
