I have been watching the unfolding news that details of LinkedIn users and their passwords have been leaked out into the wider web.  The most recent story is here.

I don't (currently) have a link to LinkedIn on my site although I do have an account, and have done for many years.  It seems sensible to at the very least to change your LinkedIn account password ASAP, and check that your information has not been changed, which as least one report I have seen has suggested.
