Hi BG. Let's stick with your first point: FREE MEMBERSHIPS.
Now, you said the site should be free, and that only pay to enter contests...
The editing tool is fun, sure.... but the main core distinguishing characteristic of MMX is the contests, interaction with the artists, and the like..
Not sure if you knew, but the jaycut editor and about 1000 other editors can be used outside MMX then the video uploaded to MMX, all with free membership to MMX?
so, your big issue is with wanting free memberships to include editor? that would be what satisfies, fills the gap?
hmmmmm.... not the social networking, not the sharing of music, videos, not the following favorite artists channels, not having one's own channel, not voting, not commenting on fav artists pages for their responses, potentially also...(all comes with FREE)
the editor, that's the gap you've identified? interesting take.
