Hi Rich Graves, I agree, that different types of 'users' eg enterprise and SaaS, have different expectations and therefore likely to see things differently in the new Yahoo! light. I also agree Yahoo! is not the dinosaur but it does have a large corporate style and approach. You may be seeing such a style with Google as it develops and things move on.
In essence, Yahoo! is not single purpose, Zimbra was. That means as the company settles into Yahoo! the decisions made about its direction are no longer just internally made for it's benefit. There will be a change in culture and expectation.
I can quite readily see that a company (Yahoo!) not used to offering local site support for mission critical services will see that as a more unnatural place for them to be. I can see them 'encouraging' enterprise users of a small-med scale to take up hosted offerings with them rather than have large numbers each of a few hundred/thousand seats on a matrix of supported os/hardware combinations.
If you want hosted solutions then Yahoo! deal will be good for you. For SaaS and smaller ISP/Enterprise clients I think there will be a change to deal with. For OSS only it may be great, time will tell, but few other similar software deals seem to have benefited the OSS one greatly. I very much want it to succeed and be good for me, I just have to keep a rational realistic hat on.
