It the adds you to a ‘huddle’ which is an empty…

As for huddles, don’t even get me started. I’m guessing a junior in the product team (or someone from marketing) said “I know let’s take…
…ack — Trashy Service Clearly an AI platform because it doesn’t work. This is probably the worst workplace app I’ve used. Rarely send me notifications at the right time.

Questions about this idea
- Is Slack Really Frustrating Poor Worst a startup idea?
- Not directly. These are complaints about a product or service people already use, and the fix belongs first to that provider. The page shows what is frustrating users and how badly — not an open market to start a company in.
- How many people have this problem?
- 8 different people described it independently, in 8 mentions, the earliest from 13 Nov 2017 and the most recent from 22 Oct 2026. The quotes, with dates and links to the originals, are in the Evidence section.
- Is this problem getting worse?
- Status: steady — no change the counts can show. 2 people raised it in the last 30 days and 0 in the 30 days before; the status compares its share of everything collected from the same source, so collecting more or less cannot create a trend.
