Networking is important, connecting is better.

Pic from the article -- generic, but it gets the point across.

I found this cool article Best Way to Introduce Yourself that I thought fit nicely with my post on meeting people on your first day of classes.
If you don't feel like reading it, the gist of it is that you don't want to introduce yourself with "Hi I'm Jacki, and this is why I'm awesome." It's better to keep it short, keep it in context, and "embrace understatement" -- as in be humble and focus on the other person. It's more fun to learn about people through having a conversation, so don't say everything about yourself upfront. Save that for your blog.
