Depends who you ask!
So I had blissfully been enjoying the clean appearance of websites without the stupid scrollbar on the right. I didn't really realize when they disappeared but was enjoying it just the same. It wasn't even a conscious thing until a week or two ago they showed back up and I'm like what the heck?
So anyhow what I thought was a feature was actually a bug in Chrome and the litter is back on the right side.
Read the article on how they "fixed the bug" here.
