If you hover over a link, you can see where it will really take you on the bottom left corner of your browser window (not necessarly true for cell phones) , for example sometimes we make:

pretty name link
some times we just paste the link:
http://steemit.com
But it is possible to trick you into
http://steemit.com

Hover over those links and find the one that will trick you into a different place.

It is just my profile, but a scammer can trick you into going to superduperscam.com

Links in articles are good because sometimes they take you a good article, or to the following article, or to other article that gives context, by hovering before clicking at least you can make sure that it is taking you to where is claiming to take you...

@patriot if you are still up to make those security series, this is something you might want to cover.
