I would donate but only if 100% of the money goes toward the projects and not social causes such as teaching x/y/z to code or an outreach program for demographic a/b/c (looking at Gnome Foundation and Mozilla here).
If you want to donate to a project (e.g. twisted, wine, whatever), 90% goes to the project and 10% goes to the SFC. The 10% is mostly covering operational costs as the SFC is incredibly helpful.
We (PyPy) are working with them for quite a bit and we spend the 90% either earmarked for the specific proposals or on sprint accomodation/travel/etc. if you don't wish to specify the proposal.
I was already considering donating a meaningful amount, but now I will donate double to compensate for the effect your absurd statement might had on HN readers.
One of the organization's staff (but not as an official activity, afaik) has a repository of filings of many free/open type organizations, https://gitorious.org/floss-foundations/npo-public-filings/ which is useful for comparison purposes, and welcomes contributions of info (most of it is available elsewhere on the web, but can be hard to find). Perhaps ought to be a website.
