Great products are built not by individuals, but by the input of many, through iteration.
Iteration means many changes, driven from even more ideas. Most of the ideas will never become an iteration. And most of the iterations will not stick around for long: quickly replaced by others.
With each change, we learn something new. Sometimes we learn that an idea didn't work the way we expected it; other times we learn something due to time passing - or our users changing.
To be able to fuel all this we need many ideas, from many different people, with different view points. If all ideas come from the same group of people, with similar backgrounds, it's unlikely we're able to build a great product.
To build a great product, we need your input (problems, annoyances), and your ideas. Yes - you, whomever you are. If you're reading this, you are the right person to have ideas on how to improve, change and upgrade our products. This is how you can do that:
There are no bad ideas. Make sure we don't miss any potential iterations, and share your ideas early and often.
If you're less confident about sharing with Product, or want somewhere to share your more abstract ideas, there is also the #terrible-ideas channel (and still none of these ideas are bad).
If you don't have an idea, but you do have a problem or even an annoyance of any size (meaning: even the littlest annoyance counts), share that instead!
Sometimes it helps to just state "I'm struggling with X", or "I don't like Y" in a channel where other people can contribute.
This will help amplify the pain, allow other people to share they might think or feel the same, and ultimately can be a start of a new idea or solution.
No annoyances are too small!
