• Enhanced privacy controls – Facebook already allows groups and privacy controls by group but right now the status update can’t be protected.  I use Facebook only for personal friends and wouldn’t want work or professional contacts to see those updates.  Hell, several of my friends don’t want those updates!  I use Twitter for my professional networking and most of my friends don’t care about the latest marketing link or new fad site.  I need the ability to send status updates to one group and not another.
• Answers – The answers feature on LinkedIn is powerful and a great way to leverage your network.  I think it leverages their FOAF feature.  I don’t know of any similar Facebook feature?
• Groups – I am a member of several groups on Facebook but none have the richness I find from LinkedIn’s groups.  I’m not sure if this is really a feature change or if it’s just about usage?
• Googlejuice – My public profile on LinkedIn gets a first page placement on Google’s homepage.  Facebook is also on the first page but I don’t have the same modular control of what information I put into Google.  I want that control – let me decide what part of my Facebook profile shows up in Google search results

Will these changes make me switch? Maybe not but I would consider it.

• Rex Hammock – Rex owns a custom publishing business and writes about the intersection of the print and digital world. He is also a great chronicler of other Rex’s on the internet.
• Dave Winer – Dave is the creator of RSS, p odcasting?, the OPML editor and many other neat thing.  Dave is a successful businessman but I love him because he’s a digital tinkerer and uses Twitter and his blog to show us what he’s playing with.
• Jason Calacanis – Jason is a serial entrepreneur and a great provocateur. He founded Weblogs Inc. and now focuses his time on his people-powered search engine Mahalo.  This week he’s offering $250K for a spot on Twitter’s 100 suggested users. 
• Fred Wilson – Fred is a venture capitalist at Union Square Ventures.  His blog A VC is always though provoking and boasts a vibrant community of commenters.  Fred funds many of the companies whose technologies I use and that alone makes his voice unique.  Sadly, Fred also gives me the heads up on cool new bands!
• Russell Beattie – Russell’s blog is an old favorite of mine.  He is a smart digital businessman and what makes me really jealous is that he tends to hack together prototypes of his own thinking.

Let me know who else I should be following?
