Is there still a market for Answer Q&A communities?

Of course, I think every organization should build a Q&A community.

• Internally it helps efficient collaboration and knowledge sharing.
• Externally it helps with customer support, user communication and business growth.

Good question.

1. Google has generally downranked user generated content for search results, so it became a lot harder to acquire traffic, which results in lower ad revenues and a weak business model
2. many Q&A communities closed their doors (e.g. Yahoo Answers)
3. Quora is huge, reddit is even bigger, Stackoverflow, dev.to and others cover niches

While it’s probably not a good idea to launch another B2C Q&A site, there is still a market. Building a c2c knowledge base for a telco, around a web product is a great way to engage users and have your staff, but also your users answer other users questions. And current Q&A scripts/softwares are mostly on outdated stacks, so answer.dev is a brillant initiative

Totally. I see this project becoming something big in the future and potentially competing with other forum software.

至少内部用是可能有市场的吧。
