The reality is, it is no different from shortened URL’s on Twitter and other social media sites. If the information in the post is detailed, and I have a reason to click the link which says “read more” or “click here”, I am happy to go ahead and read it.
If a post appears which just says “read this” and nothing else, I am unlikely to click it.
Whilst I can see there is a certain level of curiousity about the matter, the function of a working link is all that is required, regardless of how it is worded.
In short, the internet is FULL of things like this. What’s the difference unless you read more into it than there actually is?
As for the theoretical reason for needing to write the whole URL… Hmmm. By clicking a shortened link you would arrive at said URL, so not sure I can see what situation would make this different.
