Tweako is the first social news website for tutorials. Modeled after sites like Digg, Tweako is a bonanza for programmers to share and learn. There are lots of guides and resources for both Windows and Mac users.
The cool thing is that this site was launched by a 19-year-old developer by the name of Michael Stefanello. Way to go, Michael!
Implications - The site is great for people who want to learn and even people who are experts. You can help out others by creating tutorials to share your expertise. Tweako also has a section where people can ask technological questions that can be answered by the public. If you are having a tech problem, this is an awesome site to look through.
