Huh, weird. Maybe the addthis control is being blocked by some security setting or addon? Try a different browser when you get home like IE, or messing with blocking addons like noscript if you use it.

At first I was wondering if somebody just blocked it using CSS, I know I contemplated it trying to get it to work with my dumb hacks before

If we're just talking about the ones at the top next to the RMN logo, they appear in my browser (Firefox) with basically all javascript except and blocked, and tracking cookies blocked from everything. If there are any embedded "Liked", "Favorited", or "Shared" buttons that I'm not seeing, then my browser configuration is working like I want it to.
