I see that Oregon Congressman David Wu has sent a letter has sent a letter about Grants.gov’s Mac compatibility issue to Joshua Bolten, Director of OMB:
I am personally troubled by the overarching discrimination against Mac-users simply because they are considered the minority. This is an issue of simple fairness. Also, worthy projects and undertakings will be affected adversely. A sizeable portion of the research community is Mac-based or the Department of Health and Human Services (HHS) would not have delayed its roll-out. It is good governance to provide equal access to federal grant funding based on fairness and worth, not on operating systems.
