The thing is, though, that if nested quotes is the issue, how is someone supposed to easily follow the flow of the conversation? If I quote a message that replies to a prior message then the person reading my reply is only getting part of the conversation. Someone who looks only at the new entries may not realize something has already be said and post the same information that someone else did earlier in the topic. Now instead of nested quotes you have repetition of the same question/answer or information which is confusing. With all the replies quoted someone can easily see the entire conversation at a glance and not repeat what someone else has already said.
