Could the dream journal on this forum completely replace a physical one? Or would it not be advisable?

I know that most of the times dreams are recalled shortly after waking, but I find that once I go over it, it'll be engraved in my memory for the day. I have relatively easy access to the forums and can get on and post an entry most of the time.

So, even in this case, would I still need a dream journal near my bed?
