We're not fans of webclips - they're a distraction.
So turn them off, right away. They used to be acceptable when you could customise the sources and trim down to your company's news and twitter feeds. But no company in their right mind wants their entire staff, raring to embrace the cloud and lean, collaborative online working, to have the latest from 101 Cookbooks in middle of their mail client!
We can't understand why you can't turn them off for your entire company from the dashboard. (Or why they're switched on by default).
