First I love Yii and seeing Yii2 coming up ensures me I use the right PHP Framework!
As I know the core developers are busy with getting the RC done. I still think you should delegate work to take care of this webpage.
On the startpage you mention 3 projects as “reference” ->stay.com still works, Chive is “dead” and piclyf too… I think that’s not really representative!
Design is always a point people talk about… I’m not… Of course it could be changed, modernized or whatever… But I think the content issue is much more relevant.
Yii is great and Yii2 is/will be great too! So delegate the cleaning;)
