Need: As I said - I see that the OSM Wiki uses reCAPTCHA. And I think
it would be more open if we would allow comments for diaries from
anyone - not only from registered OSM users.

CAPTCHA: I'm running a Wiki and I had to lot of spam before I
integrated a CAPTCHA. I know of honeypots which are easy to hack. What
I do have in mind is a CAPTCHA which helps resolving OSM errors
instead of serving Google to translate books. But before I continue
realizing it I thought I'd ask first.

So, I'm open for better solutions if you know of any.

Yours, Stefan
