Personally, I've never had a problem with the length of your LJ posts or the time between. It sort of suits your character: wordy but busy :-).

That said, my LJ friends list isn't as busy as others and the people on there seem less likely to post their latest "Which fungal disease are you?" and "Which Batman costume component are you most?" quizzilla results. Your one entry once in a while posting style would certainly get lost in the clutter of that sort of page ;-).
