After seeing the link, I wanted to run here and say how awesome of a marketing idea this was. But then I read your comment and it got me thinking...
Within this little tech circle, I think it is great. Take something big, bad MS said; twist it, make it 2.0 and bam! Instant marketing...
However, what happens when someone else sees this website. It is going to entice them to try Zoho? I don't think so; if anything it will make them want to run far away and probably to MS.
I think they should have sat on this idea for a little longer and maybe cooler heads would have prevailed. I am very interested to see how this works for them!
