It needs to be closer to where the acronym is first introduced. The definition, on my screen, is below the fold so it can not be seen in context of where the acronym is first introduced. If it was defined below the title, I would understand.
This is a somewhat useful feedback, however I am not too sure how this can be fixed given the structure of my blog post. Do you think if I just add a line `*WSC is short for Windows Security Center` in the first paragraph this will be enough?
In this post I will briefly describe the journey I went through while implementing defendnot, a tool that disables Windows Defender by using the Windows Security Center (WSC) service API directly.
Or use the abbr (and its title attribute) that was designed for that purpose; no extraneous "flow" breaking required. Mobile people can long press on the indicator to read more, everyone who magically knew what WSC gets to continue to know what WSC means
The typical solution, is to include the expansion in brackets after the first use.
Simple rule I learned on my Electronic Engineering degree (where we're guilty of many, many acronyms): When you write an acronym/initialism in a paper (or anywhere for others to read reall), assume the reader doesn't know what it stands for and include the expansion in brackets immediately after the first use.
EDIT: As my sibling comment also suggests, writing it in full the first time, and using the acronym/initialism in brackets is also acceptable.
