My bit of deep wisdom for the day...
Requiring commenters on your blog to complete word verification and go through comment moderation, is like requiring someone to ring your doorbell and knock before you decide if you'll let them in.
I know, it's not really a big deal. Just an annoyance.
If you like to moderate comments, that's fine. Honestly, I don't like having to moderate, so when I get spam, I just delete it. If you do moderate, you really don't need word verification.
I got spam with word verification, so I turned it off. If word verification works for you, keep it--but if you use Blogger, you might consider not using "embedded comments" with word verification. The embedded comment form makes the word verification process tedious, since the comment form has to load twice--once to enter the comment, once to enter the gibberish word.
Easy commenting--it's a beautiful, freeing thing! Peace, love, and simple blog commenting! Come together in sweet unity! Let's hold hands and sing together, to the tune of "Kum Bah Yah"--"Comment here, my friends. Comment here." Comment FREEDOM!
