Funny thing this, we say 'normal people' all go for big edges, but I've actually found that not that many people always go for a thick edge. Yes, they want a bit of meat in the edge, but I have a couple of friends who are decent batsmen, and when I was looking for a bat for one of them, he said he didn't actually really like a thick edge, just wanted something with a good middle. The other guy is the same, just looks for one with the middle where he likes it. Both are more fussy about their handles and pick ups, and neither are part of this forum, at least I don't think they are. Also, there was this other guy, who likes concaving, he just said it's because bats look weird to him without concaving. Didn't really say anything about edges either...
On the other hand, I had a kid asking me to look for a bat for him, with a thick edge, because he felt his GN didn't have enough power in it. I was tempted to tell him to time the ball better and to stop using the toe and edge, but we have to be nice.
