1. In a single FB post, why do people put so many hash tags? Like on inaugural day, with a picture of their family dinner table, a FB friend put: #BidenPresident #timetocelebrate #biryani #gajarhalwa #MyPresident #GodBlessAmerica The hashtags were longer than the rest of the post. What is the purpose of the hashtags? In particular, the #garjarhalwa? 2. On places like Nextdoor, a person finds a wallet and posts, "if the owner can identify what is in the wallet, you can claim it ... meet me at ..." Three hours later, the wallet and its grateful relieved owner are reunited. People start lauding the finder thusly: "Good to see such honesty", "We need more such stories", "Kudos to you ..." and "God Bless you and your family ..." "you are setting a good example for your kids." Why the outpour of compliments? Is it a millennial thing? Shouldn't returning a lost wallet be default? Isn't keeping it a crime? If I complete a day without committing a crime no one compliments me. .
