I think, except question/answer, quello will not provide anything else to do because, as we all know, even this category is the biggest one among all, we have example of quora. Owner/Creator/Maker/Developer of the quello would be better to get that answer from though.

Also stackoverflow, reddit :) depending in the topic being asked.

Each site is has its own powerful userbase like, mostly dev/IT people use stackoverflow for coding then stackexchange for their hobbies.

People on quora and reddit are more diverse.

But quello looks promising, maybe users and the devs might discover quello's strength in the future.

Well said and agreed.
