"Open-Source vs. Proprietary. It's a debate meant for specialists. The end user usually isn't concerned at all! It's like buying a Mac and then wanting to understand, see, and maybe modify its processor.
Conceptually, Software isn't different from Hardware. And so, if you believe that all information should be copyleft, then the same should apply to material things as well!"

I'm Feed Up with Google Super-Powers
"Sorry, but even if you are captivated by the seductive functionality of main Search Engines, the truth is that they are still very poor and disappointing in their ability to provide reliable results for Linux Tutorials. Google is just Surfing the deep Web Ocean... But cause of it Succe$$$ it gives you very smartly the Illusion of Super-Powers!
Google Search indexing now got too sophisticated in the criteria requests and so often it trow away the baby with the bathwater.
- Very good in indexing very specific topics with limited number or results.
- Not good in indexing more generic topics with thousand or results.
- Not good in indexing large websites with very frequently adjourned similar entries.
Moreover, on one hand, they push publishers to write very long articles to get best ranked, making them practically unreadable online. On the other hand, then they pick the essential phrases and uses it freely at the top in the form of AI-generated reader digests.
Again, the Analysis of Original Content is quiet worthless for the Tech Tutorials field; cause there people just want to solve their Issues quickly..."
