I've just closed my LinkedIn account, in reaction to the recent announcements on their ill behaviour re. their user's data (in particular emails).
Even if I didn't allow my mail to ever pass through their servers, I think I've been their product long enough.
If I ever am looking for a job in the future, I do hope that my track record in various code repositories will speak better than my resume in LinkedIn database.
From time to time I've had the need to check on someone's profile there... but I guess I'll have to do without it.
I shall update my WebID in the next days, to complement the move ;-)
