Sorry for being bristly - or perhaps even beastly
You're right, it is a defence reaction brought about by experiences on other forums.
Who knows, I may even eventually decide that I can get away with making a reply to people who disagree with me without expecting to be told that that displays arrogance (because I can't accept that I'm wrong and need to defend my position) and browbeating (because I give reasons and try to convince).
I have come to expect that sort of thing...
I have no idea why our flickr searches work so differently. I just tried using Go ogle, and was fascinated to find a page showing my greatest hits - well, my most popular flickr photos according to flickr users!
(Note: I spell checked this, and decided to accept the correction for Google which appealed to me. Is it accurate, I wonder?)
