People whine about lack of comments. The truth is, you should simply be happy you have readers. I get 1000s and 1000s of unique visitors to my blog, yet I don't even have more than a few handfuls of GFC followers - and generally even less commentors.
Imagine a world where there was no word verification.
Makes me sigh dreamily.
Now those that argue they already get a lot of comments, you'd get more.
It's time consuming (think of those visiting this month from the A to Z Challenge). It takes twice as long to put in those little letters. And they seem to be getting harder and harder to read. There's been blogs I've simply left after three or so tries.
I know - I know.
What about spammers?
To be honest, Blogger does a fairly good job of putting spam comments in their spam bin. However, simply turn off your word verification and choose to monitor your comments.
It takes (honestly) just few seconds of your time.
A lot less than it takes your readers to try to figure out the mess that is the word verification.
