Is “bjarne” an impostor?
Probably not. Most of the newsgroup postings, interviews, etc. claiming to come from me do come from me. The obvious exception is the infamous IEEE “interview”, which I find rather unfunny. I have been known to post to newsgroups from my gmail account where my user-id is “Bjarne”; somehow, that seems to confuse some people. If in doubt, consider the style and contents of the suspect message, check for other postings in the forum, or ask.
