Earlier quoted context omitted.
I turned off comments and allow people to contact me through Twitter or email. That seems to be such a high barrier to entry that the contact I do receive is almost always because someone disagrees strongly or because they are very thankful for something they learned. In either case, it stops pointless crap like 'first'.
Just out of interest, how active was your blog? (hits/day?) I don't have a commenting feature on my blog - partly because I haven't gotten around to setting it up yet, partly because I'm worried about potential spam. But I would like to get some feedback from my readers, so that's a bit of a conundrum...
That was nearly 7 months ago I guess? Looking in Webmaster search console it says I had 15.5k clicks and 237k impressions last 28 days (compared to 17k/297k 7 months ago), so maybe there are less visitors now. Not sure.
I might turn the analytics back on at some point to find out!
