Ask HN: What's Up With The Adjective "Beautiful"?

It seems like every week on HN, someone posts a new "beautiful" project. I don't know much about marketing, but I'm interested in what effect, if any, the word has psychologically. When I did a search for beautiful stories by relevance I saw this:

    ▲ Outbox – A beautiful inbox for postal mail
    ▲ Beautiful failures - accidental 3D Prints (images & book) 
    ▲ Forecast.io (beautiful weather web UI/UX) 
    ▲ Create beautiful Javascript charts with one line of Ruby
    ▲ Beautiful Code: Another Level of Indirection 
    ▲ Three Beautiful Quicksorts (2007)
    ▲ How to build a beautiful, sturdy standing desk for $30 
    ▲ It’s a beautiful thing when free data meets free analytics
	

When I search, I rarely use adjectives and I never type in the world "beautiful". I don't search for "beautiful bootstrap login screen", I type "bootstrap login screen". I also don't search for "beautiful iOS socket library", I type "iOS socket library". In fact, putting "beautiful" in front of "iOS socket library" returns an incorrect 1st search result on Google. It feels as though search engines have taught me to be unemotional about my queries. Could I get some feedback on where this trend stemmed from and whether or not it actually matters?
