This is almost 20 years old technology has changed a lot since then.
Email clients hide quotes by default and also quote by default.
People don't treat email the same (who has the time to summarize/edit the quote anymore).
Gmail has made top posting the default which means most users will top quote.
Threading is a bit better.
Feel free to continue bottom posting but remember not to quote the whole damn thing and remember to keep the quote short enough that I hopefully don't have to scroll down to see what you added. I personally find top posting easier to follow with modern threading.
