I looked into this because I remembered weex having a different alibaba site[1]. it looks like weex became an ASF incubator project ~6 mos ago. around the same time, evan you (vue creator) mentioned on twitter (or maybe a github comment, I don't remember) that there is massive development going into weex right now. I would guess it'll be a few more months before we see a solid website with solid docs from ASF.
