Why not just market what you already got? Instead of hinging your hopes on a new feature, or a rebrand? That just seems like kicking the can down the road, a little.
I concur, all these branding ideas are pretty fucking atrocious compared to Sling. Just call the market Sling. One brand, one product -- the product is the brand. It's pretty god damn straightforward / what's the real reason for delaying here?
