Keep in mind that Vue's funding success is based on the large donors, which are less than 10% of the volume of donors. Lose even a few of those and Evan may have to shift his time to consulting.
That's the nature of the beast. Pareto/power law distributions are very common in economic transactions. 80% of a lot of sales orgs revenue comes from 20% of deals, 80% of many freelancer's income of many freelancer's income comes from 20% of their clients, etc... Many people do sales or consulting anyway.
Of course. I just hear alot of references to Vue's funding and the number of donors, which misses the fact that 80%+ comes from such a small number (you could say that Pareto distribution will always be true, so many donors = larger amount, but it's really a matter of getting the right donors in my opinion, but when budget cuts come, those projects will be first to go I'd think)
