Rhizome.org has a few days left in its fundraiser. I just donated and recommend that you do the same!
Notions of "net art" and "new media" change over time and we have nothing like a consensus on whether these even exist. Still, the idea of a digital commons where this can be hashed out has merit.
Rhizome's relationship with a museum (the NewMu in NYC) adds a provocative element to the mix: the possibility of institutional legitimacy or illegitimacy makes people genuinely angry, whereas in most digital situations the appearance of democratized crowdsourcing gives every decision a layer of cottage cheese affability.
My own writing about Rhizome was described last year by an AFC attack ninja as venomous when at the most it was mildly critical (it's all available for perusing if you want to have a venom hunt). The same ninja said my writing about Rhizome impeded Rafael Rozendaal's career!
The escalation of mild to venomous and the potential for artist career destruction would not even be considered if the attack ninja hadn't perceived something to be at stake in writing about Rhizome. This may be a strange and roundabout logic in support of donating but it's worth dollars and cents to me.
[It should also be noted that the administrator into whom I injected the contents of my venom sacs has since left the organization, no doubt limping from the effects of the deadly poison.]
