Opinion Survey - Using Adverbs

I've heard a lot of advice against using adverbs, to the point of where it is giving me a mischievous thrill to use them. That's fine for blogging and Twitter, but to what extent should I avoid them in more serious creative writing? Is this prejudice a fad that will pass?
For now, I have decided not to delete all my adverbs universally, but to examine and consider them each on a case-by-case basis.

What is your opinion on using adverbs?
