I predict they will do like this:
1. Pay up 26 billion USD
2. Stop any feature development for 2 years while they remake the core of the LinkedIn system
3. Release the ?new? LinkedIn which has almost the same features as the LinkedIn we know today (but without the finesse and also lacking some appreciated core functionality)
4. Release some new ?LinkedIn for students?, "LinkedIn for pets" and "LinkedIn for dead people" that all will flop
5. Find out that the userbase is shrinking and therefore transform LinkedIn to a simple ?Facebook plug in?
6. Fire 95% of the employees
(As a "bonus" they might screw up the posibillities to use any local language outside US. IF someone moves across a boarder, his LinkedIn account will stop working. Chronological order for this is unknown...)
The future has the answer?
Love your post... this is EXACTLY like the Yammer, Skype, and Nokia acquisition.
