Well I am trying Twitter to see how it works.
I have resisted it so far, but the ease it provides to publish quick thoughts and rambles makes it easy to use.
I am still going back and forth trying to decide if Twitter or Pownce is better, but for now, it is Twitter. Who knows, I might use both.
I have installed Twitter Tools by Alex King and will be using that. It looks the most functional and provides the best services.
Let me know what you think and let me know if you prefer Twitter or Pownce and why.
