Twitter is down and the sky is falling – what to do about it.

It looks like Twitter has been the victim of a hacker this morning as the service is well and truly down – as are most third party add on tools that integrate to Twitter.

Here’s what you can do to fill the time until you get your Tweets back:

1. Work – no excuses no distractions, get on with your work and you will be amazed at what you can achieve without Twitter to distract you.

2. Use an alternative – Facebook and Friendfeed are both working for now so try them out.

3. Update your security – if it can happen to Twitter it can happen to anyone.

4. Look up “Denial of Service” on Wikipedia

5. Call someone up and have a real world chat or even better go and talk to a real person (one you can touch!).

6. Check out Twitter’s blog which is still up and running for up to the hour updates.

7. Try something new instead – like Identi.
