Understand how more things work.

What exactly is a tag? On this website or any other blogs? How does it work and what is its purpose? What does subscribing to someone elses goals mean? What occurs when you click on that? Is it as creepy as it sounds or a normal practice? What exactly is a cheer? And how common do people get to read other people’s entries? Will anyone have read this? And if you have, and have any insight to the preceding questions, will you please help? That would be awesome…and help me take a baby step on this particular goal. : )
