Subject Re: [PROPOSAL] Accept Wave for incubation
Date Wed, 24 Nov 2010 14:25:26 GMT
A hearty +1 from the designated champion to getting Wave into the
Incubator.  I've been especially impressed with the way the community
has rallied behind the open source implementation and know that it
will do well at Apache.
