I absolutely despise those pop-up "Can I help you" boxes on product websites (usually Intercom). It completely disrupts my flow as a reader in trying to understand the product. That attention disruption got so bad I blocked Intercom and their ilk via injected CSS rules. I really want to take it a step further and write a plug in to interface a chat bot with the human on the other end and waste their time so sites beg…
Agree. Over the last few years, I started running into those more and more often as well. From an UX standpoint I would categorize them somewhere between marque/blink tags and rotating GIF icons.
Actually, that was roughly the time from which I recall first running into those things on corporate websites (IIRC Yello Strom in Germany had one in the early 2000s, widely know for a particular Easter egg).
I find it kind of funny that those are having a revival in recent years, along with animated GIFs (abused as a video format this time round) and annoying overuse of the word "cyber".
