Some other comments from slashdot and digg that I think my be good to get commented on:
- There are constant rumors of MS trying to buy Yahoo. This would now be a very very bad thing.
- Yahoo, unlike Google, likes to own their content and data. How does this fit with Zimbra's you own it model?
- Does Yahoo really have the cajones to go after Exchange in a way similar to what Zimbra has done, or will they cave the first time Microsoft dangles a unfavorable browser change in front of them?
