ExecTweets IT includes all the Twitter-powered goodness of the first version, Exectweets, but we've added more functionality and features to make it an even more useful resource. And we're focusing our efforts on helping IT professionals who make an array of projects work in companies of all sizes. (http://exectweets.com/2009/11/18/welcome-to-exectweets-it/)
I visit this site daily! I used to only check it for valuable news/trends from Execs via the twitter stream, but now, in the blog post section (http://exectweets.com/category/it-experts-blog/), there's a lot more in depth content that adds even more value to the existing community.
