"This is a really powerful tool for doing that!"
It's actually a meaningless statement. You've conveyed a sense of your appreciation for the software but you've failed to describe any aspect of the app that really supports the assertion. It's a very popular buzz-word right now and it irks me. It is often used by people who's opinions I generally respect as thoughtful and insightful, and it ruins otherwise intelligent blog posts.
I'd like to see a return to informative descriptions, many of which can be equally brief while conveying far more information. Maybe the app is elegant, maybe it is feature-rich, predictive, minimal, beautiful, complex or fun. Any app worth shouting about comes with a slew of meaningful descriptions. Let's use those instead, please?
(grumble grumble, harrumph!)
