I've never actually seen webanswers.com, but Musing.io does remind me a lot of Quora. One thing that I think Quora does really well is link you to other similar questions... you can really go down a rabbit hole and it feels like people really put amazing effort into their answers. Quora can be frustrating and annoying though, they'll send e-mails for no reason and the site just feels very cluttered.
Is webanswers.com dead? I couldn't find it at all.
Unfortunately Google can squash anything they like... and they don't like Steem... the good thing is that the Steem blockchain has it's only little ecosystem and user base, and that means that Musing.io has a great chance of success. It might struggle on it's own if Google decided that it didn't want to rank it, but since all the users on the Steem blockchain can easily answer or ask a question I'm confident it will do really well.
People are also trusting Google less and less. I've got my own Wordpress website that I've had for about 4 years... and in the analytics I can see that DuckDuckGo is growing and growing, and soon Presearch will release their own search engine, and DWebs will take off over the next few years. I don't believe Millennials are going to stand for Google's antics forever. My own site ranks very differently on Google compared to Bing/DuckDuckGo. It's usually 9th on Google and 1st on the others... because less relevant sites are buying those positions.
I personally can't wait until Presearch has a fully functioning search engine. It's going to be great!
Yes, webanswers.com is dead. After Google changed their search, it lost most of the revenue from adds and the owners must have given up. It was good until that happened. It's good that musings wont have to rely on add revenue and Google.
