Thanks to all who tested the DISQUS widget for comments. However, after discovering some issues with its handling at Safari and Opera, it was removed.
Decided to go back to blogger comments without the captcha requirement. What that means is that I will moderate all comments once again. Yuch. I'll see how long that lasts until I tire of it.
A future approach may be to have all register to be able to comment. That may be the next solution if I tire of the moderating routine.
