I don't find it visually pleasant at all when I get confused about what's quoted and what's not, and when everyone is forced to come up with their own quoting scheme since it's not supported. Some use double quotes, some use italics, some use double-quoted italics... It's a mess. I'd much prefer a consistent representation for blockquotes for ease of reading and semantics. It's the Right Thing.
