Not keen on the article at all.
It assumes that people are registering for entertainment things rather than vacuums and power tools because they are thinking about the fun aspect of marriage and not the cleaning and diy they'll need to do. It seems much more likely that most people getting married these days already have these items (shockingly, unmarried people vacuum too!). Most people don't get married out of their parents home, and already have the necessities.
I suspect the cooking and baking goods popularity is due to it being in the overlap between non-necessity fun things and traditional 'domestic' things. So people register for fancier bake ware for entertaining etc, or speciality appliances, that allow them to cook different stuff.
I must admit as a guest I prefer the idea of gifts that are 'nice' as well as practical. I prefer the idea of my friends thinking of me when they use their new wine glasses, then them thinking of me when they use their new bin...
I also find it weird that it says entertainment electronics 'wont stand the test of time' but apparently cleaning supplies will? (I think either are 'ok' on registries, but probably wouldn't do either myself).
I don't like honeymoon registries, giftcards for the wedding etc. If you don't have any physical gifts you particularly want, just don't have a registry. Guests are perfectly capable of giving you cash if they want to without you 'nudging' them into it.
