Regarding the post about the Minox spy camera, somebody wrote to me:
"Don't take this the wrong way, but I thought your column was not really worth the space and time of writing and publishing it. You don't have any particular knowledge or experience with the camera, and you've never seen any photographs made with it, but you're expressing disbelief that it could have been used for anything real? That makes it a seriously uninformed opinion. Who cares?"
Fair enough, I can see that point.
Except I was not giving an opinion, I was just expressing that there was something I didn't understand. And like often happens, lo, my readers helped me out.
When writing proper articles for proper publications (paper or online), one has to be careful to make research and only publish proper informed and considered opinions. But a blog, at least this blog, is not a proper publication and does not contain proper articles. It just contains "posts", which is a thing closer to a conversation than publication. It's very informal to me at least. It's just chatting.
Of course it may change nature from post to post. And a medium may be considered differently from person to person. I once had a correspondent who berated me for not leading in e-mails with "Dear (his name)". He regarded e-mails as letters, whereas I regarded them as conversation.
