Writing These Posts, the Blog Looked Much Fuller

Although in languages such as German (and, less recently, Latin) word order doesn't change the meaning of sentences, it is of the utmost importance in English. Modifiers that are moved to the wrong place in a sentence can totally change the meaning of the message, occasionally in ways that the writer may never have thought of.

Each of the four examples surrounding this post (I couldn't get them arranged the way I wanted) illustrates an example of a misplaced modifier. The first (upper left corner, then go clockwise) reads "After eating too much chocolate, the scale told me I had gained ten pounds." In this case, the problem is with the placement of the adjective phrase. As it is, it looks like it is modifying the scale, which is impossible. The scale didn't eat too much chocolate, you did.
The second reads "I ordered a pizza for my friend, covered in pepperoni." While this one is easy to understand, the word order can confuse people into thinking that you first buried your friend in a mound of pepperoni and then proceeded to order him a pizza. This, while awesome, is (hopefully) not the case.
The third one says "Rowing across the lake, the moon occasionally disappeared behind the clouds. The problem here is obvious - the moon is not rowing, you are. Well...maybe your friend is. It's pretty dark out there. Maybe you're afraid of the dark. Especially if the moon is disappearing behind the clouds. That makes it even darker.
The last one says "Pickled in spiced vinegar, the host thought the peaches would go well with the meat." Again, a misplaced modifier. This one presents a variety of problems. First off, the host is clearly contaminating the vinegar. Gross. Second, it's completely rude to vegetate in an acidic liquid while simultaneously entertaining guests. Third, the host probably isn't pickling, the peaches are.

So now you know the danger of misplacing your modifiers. Look for it in articles and things, since it is a pretty common and (especially now that you're informed) easy to spot.
