has a new blog. From his first post:

If you are not accountable for promises, if you try to do everything and focus on nothing, and if you obsess about aid money raised rather than results achieved, haven’t you already told us that the money will not be “well spent”?

He is talking about foreign aid, not the stimulus bill. To be fair, Obama’s team has promised specific intermediate goals (e.g., the of number of schools to be refurbished), although the results will not be measured (e.g., whether refurbishing a school leads to better education).
