Jive Overview, one of SharePoint's few remaining competitors

Jive's SBS software probably has a slight advantage in UI and functionality over SharePoint. Though SharePoint 2010 catches up with a great deal of these features, there is still a market alternative to SharePoint. Since Jive works with non-Microsoft platforms like Linux and MySQL it offers "SharePoint" for those firms not on the Microsoft Stack.

For a firm solidly in the Novell SUSE world this offers a Social Content Management without having to migrate from Novell to Microsoft. Migrating from Novell to Microsoft can be extremely time consuming and costly and returns no benefit beyond being on Microsoft. Administrators I know who work at Novell shops seem pretty happy with the set of solutions and I would first suggest they look at Jive before thinking about bringing SharePoint in to the mix.
