"Owly" over at "Letter Go" found a really useful writer's tool. The Writer's Diet
Visitors to the page paste in up to 1,000 words of their work, and it then generates feedback based on word usage. It targets specific areas of writing--namely, verbs, nouns, prepositions, adjectives/adverbs, and it/this/that/there. It's meant to help a writer get rid of unnecessary words.
My personal opinion? It is helpful. Not a panacea for writing ills, but a tool in the writer's arsenal. It's a new set of eyes on the things a writer is blind to: his own work. It highlights things that might be bettered if changed--or eliminated.
You don't have to register, and it's free. You might find it useful--you might think it's a waste of time. Either/or, here's the link: The Writer's Diet Test When the results come back, remember to scroll down to see the highlighted words in your text. It's easy to miss since it's below screen level until you scroll down.
The disclaimer on the website:
ATTENTION USERS: Please note that the Writers Diet Test is an automated
feedback tool, not an assessment tool. The test identifies some of
the sentence-level grammatical features that most frequently weigh
down academic prose. It is not designed to judge the overall
quality of your writing — or anyone else's.
Happy dieting ;-)
