Now this was an unexpected surprise. I recently received the following message:

I’m not gonna lie: it’s really, really flattering to see my blog listed on the same page (at #76) with some of the genuine heavy hitters out there in mathematical blogland.
This seems like as good an occasion as any to thank my former students — many of whom are now secondary teachers of mathematics somewhere in the Dallas-Fort Worth metroplex — for suggesting that I create this blog in the first place as a way of keeping touch with them after they graduated. I do hope that this blog has been a help.

Hello sir! Congrats to you and your blog for getting displayed in the top 100 math blogs! I too have a blog that is nominated for top 10 blogs. They however asked me to subscribe to feedspost. Did they ask you to do the same? I would have subscribed had I been financially independent but I am a high schooler, so I have no idea.
I was not asked to pay anything.
