Groove -> Office Groove -> SharePoint Workspace (not SharePoint in general)
Office Communicator -> Lync (unrelated to Groove, internally developed from the start I think)
I wouldn't be surprised if in a year or two, yammer is also rebranded under the SharePoint name as something like SharePoint TeamChat 2013 Enterprise. If that happens, it'll likely drop off my radar as quickly as Groove did.

I wonder if any of the team from UBS that were spun off made any money from the acquisition.
We use Yammer now at work and it works pretty smooth, except there is still far too much activity that happens outside Yammer that reduces its potential value.
This is where I think that there is still a lot of room specifically for Salesforce and potentially linkedin, which could do really well in this space.
Obviously Salesforce has chatter and a range of utilities that are already in this space - but still a lot room to build some amazing tools.
SharePoint Workspace, which is what Groove became is never used, anywhere.
Sharepoint may be an atrocity against good software, but it is heavily used in the industry. You would cry if you knew how much money MS makes off of it.
The product has actually improved a lot since the earlier versions that people usually associate their negative opinion of it with; and i've actually been seeing a lot more success stories than horror stories as of late with SharePoint 2010 deployments.
It's true that Sharepoint 2010 is better than earlier versions. With this version the whole edit-file-in-sharepoint-using-word scenario works probably 95% of the time. That's a huge step forward over earlier versions.
Of course, since the edit-file-in-sharepoint-using-word scenario is pretty much the only thing Sharepoint can do that still leaves it in the category of an atrocity against good software.
(Yes, I realize that Sharepoint technically can do other things: wikis etc. If you've ever used any other good product in the same space you'll find the Sharepoint implementations laughable though).
Edit: fixed wysiwyg typo.
It is the enterprise IM software for any company that has legally-imposed archiving requirements for their communications.
Nobody talks about Groove or O.C. because it's not that type of product. It's a utility, not a toy.
