I did not have time to read all of the posts.. but, I must say twitter has taken me by storm. I have made tons of valuable contacts there. Feel free to "follow" me on twitter: http://twitter.com/medxcentral When you find valuable people to follow... it's like seeing their discoveries as it happens. Just depends on what they tweet.
I useInspiration, my blog mostly as like to post if not every day, then a few times a week.
Always spend every morning on my favourite auto surf that pays exactly as they say.
