When Yahoo's Digg-like social news site Buzz first debuted earlier this year, the company opted to run the service in a rather restricted manner taking stories only from about a few hundred pre-approved news publishers. Finally six months after its launch, however, it appears that Yahoo Buzz is officially ready for business with the submission process now open to the public at large. Despite being fairly new to the social news scene, Yahoo Buzz has a significant advantage over its competitors which is that popular stories on the service can get placement on the Yahoo page itself, and the traffic-related possibilities of this simply can't be ignored by publishers.

We built Noteflight because we looked at where software is today, and saw that applications for writing music were stuck in the past. We wanted to accomplish a few important goals: Make it easy to create and share written music online. People who make music -- amateurs and professionals, students and teachers -- want to share that music with others, sooner or later. But most software for working with notated music treats the Internet as an afterthought: it's geared to saving your music on your own computer's hard disk, not to sharing your music with other people. It's painful to share musical scores online today, and as software inventors, we knew how much better it could be. People expect to be able to do their creative work wherever they go, and a crop of new browser-based applications make it incredibly easy to create and publish word-processing documents or spreadsheets online. We feel musical documents should be just as accessible. Empower developers to build a new world of musical and educational applications. Applications today should be not only powerful tools, but building blocks that can be combined in ways that their creators have never foreseen. A truly powerful musical application should be extensible without having to open it up and change the code. Adding new instruments and symbols, or embedding in a page and building new kinds of connections with other content -- all of these things should be possible. A great tool lets creative people not only use its built-in capabilities, but extend them and freely reorganize them in new ways. As Bertrand Meyer, a pioneer of software thinking, once put it: "Real systems have no top". Encourage a vibrant community of users by keeping the basics free. Music notation software vendors continue to charge high prices for boxed software, CD and DVD distribution media, and printed manuals. Then once you buy something, you're basically stuck with it until the next major upgrade cycle comes around, at which point you pa

Good day Steve In 2000 I created my on flipped an open enrollment evening college statistics class using a free online programed statistics textbook plus unique excel statistics software for homework. The top 20% (about 5 students) learned much more with less work and spent much less time in class/lab. The middle 60% had much less math anxiety, learned something but not enough to be useful. The bottom 20 finished with probably did something for their self-esteem.
