LiveJournal has a good many options to select so you can tweak the "look and feel" of your journal and friends list and such to your taste. This is all fine and as it should be. Give a user choice and let the user make the choices. Those with paid accounts get more control. No problem. That's providing value for money.
But one thing is missing. And it's a rather big omission, I think. That is a choice to see other's LJ entries and friends lists with the same style and color choices as one's own.
Some might say that would remove some individuality or such. And yes, it means that the look for someone else wouldn't be the same as the look for oneself. So what? Wouldn't the benefit of not encountering a jarring change of style or hyperactive color scheme outweigh that? And if you like an odd style and raucous color scheme, you could set it so everything looks that way to you. An inconsistent interface is generally bug. Why not get rid of this bug? But make it an option, so those who, for whatever reason, want changing colors and style can still have them.
The only problem may be one server load. It'd be one more thing for the machinery to do. But would it be that big of a deal? It already has to get the information for a look, this would mean it'd have to get it from a different source is all. It probably isn't quite as easy as it sounds, by I expect the benefit would be worth the trouble. Why, it might even be worth paying for a feature that good.
There's probably some place to make this suggestion (if it has not yet been made) but I haven't looked for it very hard - yet.
