General consensus is that the males don't bite (though I see no reason to tempt fate by testing this theory).
The female's bite is not nearly as dangerous as the press would have you believe, comparable to a bee sting? (Any animal bite/sting introduces the risk of subsequent bacterial infection, this would seem to be the basis of many of the reports in the press). Even so the females are fairly shy & docile, not aggressive. The males are often wandering around looking for a mate, whereas females largely stick to their webs.
