Any particular reason?

It seems good netiquette to help reduce the length of posts.  People should be
able to concisely paraphrase the previous post or quote only relevant sections
thereof.  Many subscribers receive messages via digest, and for them it's
cumbersome to have to wade through all those repeated messages, some even with
dangling html attachments (another habit I am trying to break). We also have
overseas subscribers who have to pay for connection time. Several posts go
through numerous responses and arrive dragging a monstrous tail of multiple
levels of quoted messages.
