Live by the sword die by the sword
Edit: To make this a more meaningful post, I don't see how doing a 180 on your content ever works out.
Lets say you do it "correctly" and own the haters.
Now you need to build up a new audience from square 1 with no idea of the staying power of that new audience.
If they leave to "new thing", you are fucked.
If your 180 doesn't work you plummet in views and either live in 2view territory or come groveling back to your old content.
GFE or no, I just don't see how its ever worth it, best you can do is slowly make changes over time rather than...
BLACK ON WHITE ANNOUNCEMENT STREAM FUCK ALL YALL which is what most of these videos seem like.
