There is nothing in this world quite like when your computer or social bookmarking site tells you that you are stupid:
You can’t subscribe to your own site!
Looks like you’re currently signed in as the owner of this Xanga site. You can’t subscribe to your own site… you already get updates from your site, instantly, as soon as you write them.
What if I wanted to subscribe so I could see what my updates look like? sigh. Alas, I resign to not be my own friend.
