I wasn't particularly looking for an argument against top-posting. In fact, since very few of my correspondents are technically-oriented, I'm on the verge of giving in. But here's Rhymes with Oranges today:

I prefer interleave posting to either top or bottom posting. But then all this depends on the situation.
If I'm making a quick responce to an e-mail that will require no further correspondence I'll top post (easier for the receipient to read).
If I'm answering several questions in an e-mail I'll interleave
If I'm on a forum or newsgroup where bottom posting is the norm I'll bottom post.
+1 on the fact that interleaving is the Right Thing To Do, after trimming the quotes to the minimum amount needed.
I don't agree that top posting is easier to read: you may think that no further correspondence will be needed, but maybe the recipient won't agree, and you'll start filling the bottom of the email with a pile of old mails in reverse order, and good luck if one of the messages is long enough to require interleaved answers.
For short messages that don't really need quotes I usually leave just a line of quote to remind what the topic was, but just skipping quotes is also good (and probably easier to do on a phone).
Of course, I use a threaded mail client, so if I need to read old messages I can easily do so (and I don't risk missing pieces in a multi-person conversation because some replies don't include some of the messages which came more or less at the same time).
Why does Thunderbird/Icedove default to replies on top?
