Lately, i have seen so many glitches happening on social networking sites. Starts with Plurk which unable to display any comments received by others. I had the solution by clicking the number instead of the plurk status, and it worked. I guess it's fixed now.
Next and the latest glitch i encountered today is in Facebook. The glitch is when you tried to access someone's profile, but you will get no profile found instead of going to the profile page.
Let's just hope they fix it as soon as possible, since it's quite annoying.
