A long time ago (so long ago actually, the original post has disappeared during one of my changes of blogging service), I predicted that Google would take over this small startup that offered online make of Powerpoint-like presentations and put that stuff into Google Docs. (I can't even remember the name of the service: it's *that* long ago ;-))
Google eventually built it's own presentation software into Google Docs, but still it's a half win for me: they did add presentation software to Google Docs.
I'd like to offer another small prediction today, be it with a little less bravado. I'd like to predict Google will eventually either build or take over a concept similar to this. It's obviously bloody brilliant and very useful, whether you use it alone or in a group.
