A thing that takes you from one place to another, in this case, from the land of "where you currently are" - to the land of "I know Kung Fu!"
Twitter gives you:
The ability to learn from people you would never normally meet.
How do you twitter?
In order to Twitter - you have to buy into the concept of:
"You only get what you give"
Once you have that down - it's easy. When you're at your computer, or you have your cellphone on you - write what it is you are doing. It doesn't make any sense until you start, but if you truly believe that you get back what you give, you'll do fine. Don't worry about what you write, how you write it, what you write it with or where you write from - just write. If you continue doing it, you'll get better at it - just like learning how to read when you were a child or like learning how to walk, even if your legs are a bit wobbly! There are many tools that make it easier to do like: Flock - it's a browser with Twitter built in - I'm blogging with Flock right now Foxytunes - my favorite tool - one click and you're away - highly recommended for Music types.
What's in it for you?
Information in bite-size, easily digestible chunks. Not just the usual suspects either, but cool things like missrougue's original post. I wonder what the world would be like with a LoveDAQ - I don't know - it feels a bit wrong to me - but then I'm a hopeless romantic.
