The FAQ currently says this website is for people who use Blender to create 3D graphics, animations, or games. However, Blender is a full-featured and very competent video editor. Especially since the release of Tears of Steel, the software is a state-of-the-art special effects tool for live action film. Should questions related to non-animation video and compositing be allowed, since this is a very large (although lesser-known) feature of Blender?
No it is not, the site is about Blender, if topics such as the compositor, tracker and the game engine are on topic, so is the vse. However, the question must relate to a problem within Blender or with Blender's VSE and not about just video editing or video editing techniques etc.
