>only the editor knows who wrote [the reviews]. This is not entirely true. I've talked with several people involved in research (math and CS). The ideal is that only the editor knows who wrote the reviews. However many fields do not have that many people who are qualified to review cutting edge results. This means that it is possible to get an idea of who your reviewer is based on how he wrote. Of course, although the people I talked to said they often can figure out who reviewed them, they cann't actually confirm that they are right (and I definitely cannot).
