Twitter. What do you think of it? I have to tell you... you need to sign up for Twitter. I also downloaded TweetDeck, which is soooooooo great!!! It updates my Twitter and Facebook at the same time... which can save so much time... I can go to TweetDeck to see what's going on both of them... I love it!!!
The thing I like about Twitter, is people share more links there than on Facebook. People link to great ideas, inspiration, etc. It also a bit less overwhelming. If you haven't started tweeting, I would recommend it. Even if you don't want to tweet, you can follow people and learn lots. You can find me HERE.
