Basically its a shortcut that would update any social media feeds like facebook or twitter. If you have the widget on one of your homescreens you can simply delete it and don't have to look at it any further.
I threw away that whole screen. I don't use those widgets so rather than leave the page I deleted the whole thing. I think you double tap home and from there remove any unused screens. Probably the best way around it. But my Gingerbread knowledge is fading since I've been on ICS for a while now so don't trust my word as Gospel.
