I'm in Bristol, England, and Careers appears to know that (my Profile page shows "Bristol, England"). Whenever I visit the homepage, though, Careers shows a section for "jobs near worcester".
Now, I'm sure Worcester has a lot going for it, but it's a relatively small city more than 50 miles away from where I am, so I'm just curious as to (a) why Careers is so keen to show me jobs near Worcester, and (b) if there's any way of telling the homepage to show me jobs near where I live, instead?
EDIT: I've since checked Careers from work (dangerous!) rather than home and it shows me jobs from London, which is even further away from me. So I guess it's ignoring what I've specified and guessing, wrongly, by IP address.
