Alliteration in captions/titles doesn't dispel your lousy writing.
Alliteration is a little game usually learned around 5th grade, employed until stale (by 6th grade it's stale), and then left alone for other juvenile minds to plunder.
You can just hear those "journalists" now, when hunting-and-pecking their next alliterating sentence or title:
"Man, look at that. All the words start with the same letter! How creative am I? Maybe I should be writing a novel!"
No, I don't think so. Unless by "novel" you mean a modernization of "The Little Engine that Could." That's about your speed.
Shame you can be so quick on a bike, but so slow at the matter of composition in the English language.
