Welcome to the Daily 5, our lighthearted look at the business news that amuses us.

Yesterday, social-networking superstar Facebook held its developer conference in San Francisco. To commemorate the event and the introduction of Facebook Connect -- a single sign-in system that's roughly equivalent to Microsoft's (Nasdaq: MSFT) Passport, but for the social Web -- we take a closer look at social networking generally, and the digital heroin known as Twitter specifically.

Here are five signs that you might be addicted to this (ahem) "micro-blogging" service. Drumroll, please:

5. Your doctor prescribes a daily diet of triple-shot espresso as a relaxant.

4. You actually know a guy named darthvader.

3. Latest entry: "flushing."

2. You binge on Facebook (or MySpace, or LinkedIn) every time Twitter suffers an outage.

And the No. 1 sign that you're addicted to Twitter ... You just changed your middle name to @.

The book on Facebook
Twitter may be extreme, but as a concept, social networking is pure Web -- born of the network effects model that eBay (Nasdaq: EBAY) pioneered. To us, it's a business tool in the making.

Think about it: There's a thin line between Blue Nile (Nasdaq: NILE), The Knot (Nasdaq: KNOT), and LoopNet (Nasdaq: LOOP) and Facebook, MySpace, and LinkedIn. Every one of them is social in some form. MySpace unites music fans; Blue Nile unites the soon-to-be-betrothed. And the big money is betting on both.
