Quoted: Here is why I would not consider Yammer a serious start-up:
...
1. No barriers.
2. The incumbent can replace their advantage way too easily.
3. No natural early adopter. The normal early adopter is on Twitter.

IBM's enterprise social bookmarking...

Quoted: Dogear exploits the enterprise by allowing people to bookmark pages within their Intranet. In addition it uses enterprise directories to authenticate the user's identity. This allows people to find experts on specific topics within the company. For example, a employee looking for someone knowledgeable in Java can look at the dogear "java" tag to see who has been bookmarking pages around that topic. Dogear will also show tags associated with "java," which may help to refine the search. Once users have found a potential expert, they can see that person's bookmarks, internal blog, and contact information. This form of expertise location helps spur collaboration and sharing of resources within the company.
