Hi everyone, there's something really wrong with the hard drive on the server that houses the activity feed, which is why there's been so many errors recently. The data center is going to help try to clone the drive to a new hard drive, which hopefully will work. In the meantime I've removed the feed section of the profile homepages, so in case there's an issue again, it won't break your profile pages at least. Just be aware that because the feed is integrated throughout the site, IF there's an issue again while the server is being fixed, it may effect other pieces that i'm unaware of (for example, it may affect setting statuses if that database can't be reached). I have to go in to work tomorrow, but will try to get back to you quickly when I have status.
