I found this recent article by Jeff Carson in Worship Leader magazine very enlightening. He points out three things that a lot of worship leaders do, often without thinking about it. What I found most interesting is that we might even do these things on purpose, thinking it's making for a better worship experience. However, as Carson points out, we may not be doing what's best for our congregation. Take a look. I think a lot of us will find we make some of these mistakes, at least to some degree (and maybe a lot!).
