Why is so hard to reach a nonprofit development department office on the phone?

Jeff Brooks is so right. At Donor Power Blog he laments about how most nonprofit websites, rather than facilitating donations, are actually hindering them.

And it not just websites. Just Friday I attempted without success to reach Development Directors at two major San Francisco Bay Area community health centers. Neither agency website contained a staff directory or information on how to contact the development department directly, either via phone or email. Both main phone lines were answered by automated voice mail systems that offered no transfer options. Instead, by default I was dropped into a general voicemail box, where a recorded voice told me that my call would returned within 24 hours. Frankly, today that is too late.

They won't be getting my donation. What about your's?
