As a startup employee, I'm curious to know how much do employees stand to gain from such talent acquisitions?
Everyone who joined Twitter was handsomely rewarded for their hard work and their accomplishments at Posterous. We're taking much of what we built at Posterous to make Twitter a more powerful platform.
If the employees simply got to keep their job, they wouldn't have accepted the Twitter offer and instead have joined another startup. There are plenty of great opportunities out there.
