One of the most interesting usages I found on using Twitter is being able to keep up to the ideas and thought of the most influential people on the IT business in a pace that would never be possible by buying magazines, articles or RSS feeds.
So I built a list with the top 10 most interesting people to follow if you are interested in IT, internet, programming, geek stuff etc. You can just check my twitter list with all of them or read below.

LinkedIn has announced today that they have released their API to allow developers all over the world to create applications that integrate better with their service.
All you have to do is access the LinkedIn Developer Network, get an account and API Key (to be used with the oAuth protocol) and you are good to go.
