Ok so a lot of people are gonna hate me but, let me tell you what I mean before you start attacking me. For starters I don't like 3.0. This may seem weird, considering what this studio is about. So let me tell youi why I support this update.
This update will ensure Scratch will outlive Adobe Flash. Scratch 2.0 (The current scratch) is based in Adobe Flash. Scratch 3.0 is based in HTML5. This allows Scratch to continue past Adobe flash. If scratch doesn't make the move either we could lose Scratch completely within a couple days of Adobe ending Adobe flash or our projects would slowly disintegrate and Scratch would become a broken webiste.
Also if you don't like 3.0 you can always download the offline version of 2.0 and then upload your projects to 3.0
Even I have the offline editor
l'll even provide a link.
