Hey @bryan-imhoff, sorry for the late reply. Since this comment I've learned quite a bit more and met Kevin Zou and Eric Chen from the WeKu team in a video conference. Its legitimacy has increased quite a bit to me due to that, though I still feel they have very significant hurdles to overcome.

The reason for the different domain names is they have rolled out Communities like Steemit plans to in the future. Everything's on the same chain, but the front-end filters the posts out separately, so if you post on one, your blog will appear blank on the others until you engage there.

1. Deals.weku.io is the main site, for now.
2. News.weku.io is the Chinese portal. They have implemented the ability to create tags using Chinese characters, something Steemit at present does not offer.
3. One.weku.io yeah... I don't actually know what this one is intended for, lol.
