I don't think it's loneliness -- I think it's a stark contrast to most of the other major recipe collection sites out there that are visually cluttered.
I think that's a refreshing change for this type of site; You may want to consider a means of allowing users to curate and discuss recipes on sub-domains, some kind of API or some other means of splitting it up? A kind of crisp, clean social platform for food prep ....
I don't seek more flashiness or colors. I actually appreciate the simplicity.
Thoughts on what the feeling could be rooted in:
I Think it would help with more than 3 recipes on the front page. That gives a feeling of emptiness that can be confused with loneliness.
I also think there could be a better choice of image cropping. One that does the trick of making them all one size, but that also lets me see the food and thus inspires me.
I'm currently the only person who can add cards to the list. But just email me at [michael] at [herrmann] dot [io] and I'll add your suggestions/bug reports!
Some say the issue of capitalism (and other social and economic theories) is that it makes the presumption that humans are rational, which is a pretty crappy simulation of human behaviour. Could this be an improvement on that?
A weird piece of feedback: Something about the UI gives me a substantial feeling of loneliness.
