What i love:

That ideas flow fast and furious. It is open. All you need to be involved it a laptop, a connection and imagination and energy.
That people share these ideas and the more you share the more your receive. That there is a community. That authenticity rules.

What i hate:

The flame wars so obviously meant to push eyeballs and get attention. It works, but it gets old pretty fast.

You can find both love and hate in this Gillmor Gang podcast. I love the complexity of how to actually filter twitter. How do you make a firehose manageable for the mass? I hate the way they go about whining at each other like a bunch of high school kids. Its like a bad episode of 90210 meets Intervention.
