Top- posting (as hated in Linux/Unix circles as it is) is good for short replies that don't lead to a long extended discussion. But bottom- posting is awful: it has all the disadvantages of top-posting, with none of the advantages.
The whole point of quoting is to provide a frame of reference for the reply. The most effective way to do that is in a conversational quote precedes reply. The primary issue is selective VS mass/pointless quoting. In many cases, quoting a single relevant block of text from the parent post is plenty. It's too bad email clients don't work like some forums where you can highlight/quote/reply to a selected block of text.
...I have no idea of the specifics, but there are some email clients where that option is/can be automatically enabled when message text is highlighted prior to hitting reply, e.g. Thunderbird, Claws, OSX/iOS Mail. It was briefly a Gmail feature, then a Labs option, now?. I'd love to hear of others, I couldn't find any webmail clients with this option (surprising considering javascript/bookmarklets).
