When I first joined this forum the word "bricked" wasn't even part of the Droid vocabulary. Even after rooting came out it was only mentioned as a caustion.
I'm not advising anybody not to root their phone, overclock it or not to do whatever you want with your phone. I would however tell you that I sure am seeing a heck a lot more of the the work "Bricked" in thread titles and on the ones I do read they certainly do appear bricked to me.
I would probably say to those who are thinking about rooting their phone that at the beginning of the talk about rooting it was recommended that only people with advanced knowledge attempt it. Now I see threads that say "Rooting for the Noob" and I check that out and there are 50 steps involved. That to me is a lot of chances for something to go wrong.
If you're going to root your phone make sure you read everything before hand and that you understand what you are reading. If you don't then it may be in your best interest just to stay away from it.
Getting off my pedestal now. Feel free to comment.
