Hello,
You're probably not gong to like this but in the interests of constructiv criticism I'll share it anyway.
I was using OLW a lot until recently. Principally my fiance and i were using it to share a spreadsheet that we are using to plan our upcoming wedding. That was until we got onto the Live Mesh beta.
The whole premise of Live Mesh (sync) is simply killer and OLW doesn't have anything that competes. If I make a change to a document the updated version automatically appears on my fiane's computer - you can't compete with that I'm afraid. As Mesh matures I suspect that everything I do online will be through the Mesh somehow. OLW does still have some useful features (e.g. Ability to permalink to a file, ability to view an office doc in a browser, ability to share a file with the public, version history) but these pale into obscurity alongside Mesh. if you can find a way of getting the differentiating features of OLW into Mesh somehow then I'll be very happy.
The title of this post is actually not true. I DO still use OLW to share my CV/resume with whomever wishes to see it and the reasons for that are:
But for most things I'm going to be headed for Mesh. Sorry.
