Gonna trim my litany of complaints about modern trends down to my top 4 gripes:
Websites that look like CVS receipts with their excessive left/right padding. Some L/R padding is desirable, but the degree to which it’s done now is typically done to cram a bajillion ads in the margins.
Excessive padding for UI controls. Looking at you, specifically, O365, but others are guilty as well. I use a desktop with a precision pointing device, so I don’t need or want a UI designed to be poked at by hotdog fingers.
Unhelpful error messages. “Oops, something went wrong”. Ok, but it is it a “me” problem or a “you” problem? Should I do anything, take any specific action, retry, or just twiddle my thumbs and hope someone else fixes it?
Chatbots that pop up on websites asking if you need help.
Bonus: Any time an email, website, or other online source has “click here” for a link. It’s 2023. People know what a link is and what to do with it. All that “click here” says is you don’t know what you’re doing as a designer/publisher.
