I agree with @neblu. When I joined Steemit I was completely unaware about steemit ecosystem. Hence I asked lots of people on their different posts such as how can I complete achievement tasks etc, but didn't get any response.

It was really difficult for me in the beginning to get to know this platform. As a result, I was quite frustrated and got demotivated to use this platform or even promoting this to others as it seemed so difficult.

So I believe if this feature comes into existence, people can communicate quite easily, and it will be helpful for newcomers particularly.
