Without a cultural change SOA 's Value Proposition could be turned to nothing, because SOA's benefits such as Service Reuse will not take place.  In a recent ebizQ webinar Gartner 's VP Distinguished Analyst Yefim Natis , talked about SOA Proponents’ Myths. 100% Service Reuse is one of these myths.

Despite of my opinion on e-mail technology when I was asked for my opinion on the question appearing in this post's title, my opinion is that Google Wave will not make e...
