So if you see Bruce Schneier asking random questions like "How encryption works" or "Please help me to install GPG" it will be OK for you and you won't google his name to discover who is that person ? Now who cares who is Bruce Schneier (the rest 10%), let's just help him with the encryption because he seems to be casual computer user.
