First off, they emphasize these ridiculous social networking style features. "Connecting to people". As if you don't know who the members of your team are.
Well Yammer is a new feature. People in large companies often don't know the other people in their teams. You may not have worked in large enough organizations where this is a problem.
. If you are such an MS house that you have Sharepoint, then you already use Outlook as your primary written communication tool - no one is going to switch over to Sharepoint for collaboration unless you take away Outlook, or unless MS spends some time actually integrating Outlook with Sharepoint in more than a token way.
Email is a 1-1 or small-small collaboration system. Document management is many-many.
I still don't understand how Excel/Word/Powerpoint losing data when saving to a Sharepoint site is not what you would consider a major problem with the client software, but a configuration problem on the Sharepoint side. A failure to upload should trigger some kind of fallback to local storage.
Because that's not a SharePoint problem it is a SharePoint as you have it configured problem.
IMHO, you need a dedicated librarian on each team if you want to use Sharepoint (or similar metadata based tools).
I don't know about dedicated but yes you need at least one person in each document creation group who sees SharePoint as one of their core job functions. The librarian is more at the level of integrating across the company. It sounds to me in your description like your company might be too small to have the sorts of problems that SharePoint is designed to fix.
And God, the lock-in. It's bad enough that we have these legacy wikis running - now in emulated hardware purgatory. But at least they are running in a VPN somewhere in purgatory, requiring no admin time and not requiring any license fee. Our little failed experiments can wither peacefully and cheaply - only accessed when old data is needed for reference. But this Sharepoint stuff, if they decide to stop paying the fee it is gone. I'm sure you can export it in some manner, but what a mess.
No argument there. SharePoint is a serious lock in. The companies like yours who are using it wrong have much less of a problem than the companies who are using it right. It will cost those companies a fortune to get their data out. Most likely they will be on Share Point forever.
