I used to work in AOL's UK office. You have a point, talent retention is a problem, and it's not because the staff are being poached, it's because this company has political battles with massive knock-on effects on employee morale and loyalty which is causing people to flee.
This has happened (and continues to happen) at AOL UK, and I feel for Jason because when you read his post, you see how sad he is to be leaving TC.
There are some really lovely, funny, supportive, and wonderful people at AOL, and to leave them behind is really hard. At times it makes you angry, and you want to blame someone for it, and sometimes you want to write a massive rant about all the shit you saw at AOL and email Business Insider and watch corp comms go into overdrive. But in the end what does it give you?
It's better to say "onto better things" - just look at the Verge... I'm sure Topolsky is glad about leaving Engadget and doing this project.
