Since there is no way to preview a message (yet! it would be for another feature request), I end up editing my messages many times. And each time, it adds a line in the activity log.
One solution (besides being able to preview the message) could be to add the activity log item only if the last editing was done more than a few hours or a day before... It could be configurable but I don't think it would be very useful though. Let's say it could be configurable by modifying the code :)
