Sometimes bottom posting makes sense, but other times top posting seems better.
I usually only read RCM once a day. Se I read more than one message of a thread at a time and would prefer to just read what is new in each post, rather than have to read down through all the stuff I have already read.
To take it to an extreme, consider what it would be like if no one ever edited out parts of the previous messages. With bottom posting ,you would have paragraphs from previous messages followed by something like " me too." With top posting you would read the " me too " and realize that you had all the pertinent information and skip on to the next message.
So I tend to top post and then in case it is not obvious of what I am replying to,include just the part of the previous message that the reader needs to realize what I am replying to. I figure that most of the people here can remember what I said long enough to corrolate it to what I quote. And that even more don't even need to read the quoted part to understand what I am saying.
In this case I am either top posting and not including any of the previous messages because I think none of it is necessary for you to follow my thoughts. Or I am bottom posting with none of the previous stuff included.
