It seems like everyone's adding their two cents on what newgrounds is or should be, and while I did buy the supporter thingy and would have if it costed more, I think there are some ideas being pushed by users that ring a little wrong to me. Ideas like newgrounds needing to move into the mobile market, or sharing links easier, etc.
Also the following is purely my own opinion based on my own limited observations and experiences.
Newgrounds is what it's catch phrase implies, 'everything by everyone', it's first and foremost a place for creators and creatively inclined people. from that follows the audience. It is not the place where the big-dog sponsorships are given out, it's not a cutting edge competitor for either videos or games because it dabbles in so many different areas.
What brings me to newgrounds is not the occasional game I play, song I listen to or animation I watch, though I do enjoy that, sadly the internet is so vast now, and other websites so carefully crafted to specialize in those things individually, that I find myself in other places when I look to fulfil those needs.
What DOES bring to newgrounds is the creation element. Game jams, movie jams, competitions, people PMing me asking for tips or advice, finding people to work on a project with me, or sharing progress of a project I'm working on. I honestly believe that at its heart, THIS is where newgrounds' strength lies.
If this is true in a broader sense, then relying on advertisements might cause NG to always be left in the financial dust of the bigger and more specialized companies/sites, but this recent push for supporter contributions has me thinking a bit. In looking at the list of contributors so far, I notice more and more that it's made up of either A) creative contributors to the site OR B) long time invested members, familiar with contributors and the NG community/staff.
I want more than anything to see NG success, because any success I could claim in my career I stem solely from newgrounds and its influence in my creative development. I think the way things are going, ads are less and less the way to go, since the rate competitive websites are growing at far exceeds newgrounds, thus NG never has the upper edge.
HOWEVER the loyalty of contributors will always be there, and I feel that if NG were more tailored to fit those needs for the supporter contribution, not only would you get these support payment purchases from already loyal creators or visitors, you'll draw in more and more creatively minded people from elsewhere. For examples, when 'Swivel' is released (a SWF to video conversion tool), easily something flash animators REALLY would love, NG familiar or not, making the program apply a small NG watermark unless they are a NG supporter would both support the justification of spreading the software, but call attention to creative people to a creative community, and give them more intensive to become a part of it, especially if there were other perks to the supporter badge, IE exclusive forums, shorter judgement periods on the portal, creative resources and API tools exclusive to NG supporters. It would turn a donation purchase into something they gain from, being pulled in for one thing and gaining access to creative tools in more areas than they know how to do with.
If the creative side of newgrounds expansion is focused on and pushed more than ads, visitors and sponsorship, focused instead on things like regular jams, with prizes (spending NG money on game jam prizes instead of sponsorships as much) the place would begin to flow the creative juices it already encourages. Get the Lit portal out there, show writers around the web there's a door open for them to contribute and get attention and even prizes for their contribution and collaboration with other artists.
Anyhow, they are my random ramblings. No real point to them, other than I'm happy to see an option to repay NG as a contributor for all it has done for me, and think if there's a direction to go in that will help its growth, this is somewhere to look at more, but adding more insentives to draw in creative people from elsewhere instead of the already loyal people.
