if you are from the sort of family/community that shows support by providing food, this is actually a great thing. though if you are from a different sort of community, i guess it would seem odd.
where I grew up, in the American South, taking food to families in short term distress is a big thing. a BIG thing. not just your close friends and family, and church, but co-workers, other parents at the school or children's activities, neighbors. it's just the thing that is done.
Her church uses such a website to help organise the many kind people who want to help the family by providing meals for families struggling with death, illness or injury or new babies. It means those wanting to give won't overwhelm families/new parents with more visitors than they are fit to see dropping off more food than their refrigerator and freezer can handle. It saves food waste, not to mention wasted effort. I hate the idea I might go to the trouble of making something, only for them to lose track of it in stressful days and end up throwing it out, green and moldy. though I don't live there anymore, and rarely take any food to anyone, as people think I am weird to do so.
we experienced the program as recipients after my dad's death. donors had the option of choosing a specific day to donate, those who wanted to give foods for use at the wake (or breakfast, see below) used this. Or donors could list a dish, and days for us to choose from, we just had to give 24 hour notice. so, as more and more relatives drove and flew in and filled up more and more relatives homes, mom could let her kind friends know the time their gifts would be most useful. 3 nights before, my uncles cooked vats of soup at moms house, so mom 'accepted' gifts of breads and desserts. the next night, she accepted numbers of casseroles, meat pies and pasta dishes, things that could travel easy and those same uncles popped in to take a share to feed whoever was staying at each of their houses. the morning of the funeral, we had hungry children and teens, but adults too stressed to cook (or clean after them cooking for themselves) even if we had the energy to go to the store. so, fruit bowls, more baked goods, quiches, and such were dropped off the night before. before the app was used, nobody really thought about sending breakfast foods, just suppers and appetizers/desserts for the wake. But thanks to this system, we never ran out of the things like bread, milk and coffee and cereal, you hope are in the house first thing in the morning, despite having as many as 17 people in moms house, and 32 more at the uncle's who lived nearby, and another dozen or so at uncle's who lived further out. plus hot breakfast the day of the funeral. there is a group of older widowers at the church who collectively donate disposable dishes so the families don't have to go get any, and won't have to wash so many dishes.
a more old fashioned paper system in the church office helps those who want to volunteer for things like setting up before or washing up after the wake in the church hall, or other physical assistance. My mom had 5 kids, her brothers and their kids, but some widows/ers need a hand getting the house and yard in order before a funeral.
the system also helped us to know who to thank for what and who to return dishes to.
there were still random things brought to the door, but they tended to be things unlikely to spoil as they came from neighbors and casual friends who wouldn't have known any other way to be in touch.
