The topic of this post is content, and what your content says about you, the author.
Believe it or not, it says a lot.
The topics you choose tell your readers where your mind goes to wander, where it tiptoes through fields of daisies, or tapdances through minefields. (The latter is to be avoided, you tend to end up minus some limbs.)
Personally, I prefer to tiptoe through minefields, but hey… that’s me.
The crux of the matter is this: What you post is out there for all to see. Once it’s out there, you can’t take it back. Even if you delete it, some search engine probably already archived it someplace you can’t demolish — even if you want to.
