Can you blog about anything?

My daughter saw my back end the other day.

Of my blog – the back end of my blog. The bit where I write stuff.
Jeez. I need to make these things clear up front, hey?

We had a short conversation about blogging and she asked whether I could blog about anything. Could I, for example, blog about the glass harmonica she learned about at school?

This one?

The glass harmonica, also known as the glass armonicaglass harmoniumbowl organhydrocrystalophone, or simply the armonica or harmonica (derived from  harmonia, the Greek word for harmony).

You had me at hydrocrystalophone.

Well, yes I can. And I can even share a video of one being played.

This is the original, mechanical, sideways version of those wine glass street performers that you see in tourist areas of major european cities. The design is credited to Benjamin Franklin back in 1761.

So yes, my dear, I can blog about anything. The world is my whelk.

Whether anyone reads it is a completely different matter altogether, of course.
