Blog Series Goals

My contribution does not claim to replace or supersede the document. Readers may want to look at my articles as inspiration to decide whether an innovation is worthwhile for their use cases and then take a closer look at it.

I will write the articles in the series well in advance to ensure weekly publication. However, due to editorial constraints it may happen that no article appears for a week.
