One of the great features of a blog is the facility to provide comments and create discussions. But this feature has been rarely used on this blog and the few comments that are posted are invariably spam. So, this afternoon, I have enabled the verification feature on comments so that whenever anyone provides a comment they will have to enter a designated word to prove that they are human (and not machine generated). If this doesn’t help to cut down the spam, I will remove the comment facility.

I hope that this does not deter anyone from providing comments. Although it is under-used, it has tremendous potential for generating discussions.
