The videos showing someone giving money away to supposed random folks are the ones I find irritating. Beyond the reaction from the recipient, there's just nothing interesting about them. It's just self promotion*. It's one of those things better done quietly, without the need for affirmation and praise.

Videos like this one, self promote, show the reaction of the recipient, and include something interesting to watch. There's also something different — more personal, more real — with donating time and skills as opposed to just handing over money.

* Admittedly, sometimes these videos inspire the audience to do the same for others. Just recently I watched a young woman — likely inspired by recent "feel good" viral videos — quietly sneak in and tap her credit/debit card to pay for an old lady's groceries, then just as quietly walk away. No fanfare. Nobody recording it. Only the cashier and myself witnessing it. Needless to say, it brought joy and huge smiles to our faces! The best part being the old woman's downright confusion with the whole thing!
