I've hated word verification for as long as I've had it turned on. I really wish Blogger had full comment moderation (that is I could delete comments or edit them, like removing HTML links). When I started blogging I quickly got comment spam, so I turned on word verification (being the only way I saw to correct this). The other option is to do comment moderation (which means I need to log in and approve all comments), but I'm not nursing this site to make that an enjoyable experience (would you like to comment and then not see that comment show up for a day or so? I wouldn't).
Camille, though, has turned hers off, and so far things look okay. So I'm going to follow suit. If comment spam becomes a problem, again, I will turn it back on. Comment spam doesn't do anything for my readers, and it mostly is to spoof the search engines into counting more links to sites and so push up ratings (which I find reprehensible).
So word verification is off. Don't make me turn it back on. And Blogger, give me real comment moderation tools!
