Last year I talked about weeding out words I overuse, and I'm still working on a replacement list for the one I lost. However, I discovered a neat trick when I began playing with Wordle, the ultracool online word cloud generator.
When you're editing a scene or chapter, open the Wordle Create Page and cut and past your text in the top box (right where it says paste in a bunch of text.) The resulting word cloud should look something like this (for a layout like this one, choose "Horizontal" under the Layout menu just above the generated wordcloud):
The words that show up in the cloud as the largest are the words you've repeated throughout the text you fed to Wordle. If one of those words is a character's name (like Jessa in mine) that's obviously not a weed word. On the other hand, if you see words that are the same size as door, around, saw and long in my example, those are words you've overused and may need to weed out.
Another thing you can do is use Wordle to generate some keywords from your story text to give you title ideas. Just do the same thing as above, but this time take the interesting/descriptive words and make a title idea list.
For this one, I'd probably start with words like Savannah, blue, sapphire, time, eyes, sweet, watch, sunrise, night and loved, play with them and see what appealed to me, like Savannah Blue or Nights in Sapphire.
