I have added ReCAPTCHA for commenting, as I get too many spams from robots who tell me how wonderful my blog is.

I used ReCAPTCHA since it is maintained by Google and better than ones made with less effort.

The flip side is that sometimes the words do not appear very readable, so can you please reload using the reload button (circled in gray above) – if that’s the case.

As a reminder, I love getting comments but don’t publish them and interact with the commenters on email.
