At Econbrowser, James Hamilton has a rather distressing roundup of recent economic data.  The already sluggish recovery has slowed down, he says.  Manufacturing numbers are getting weaker, housing prices keep going down in most markets, employment may not have hit bottom...all leading to meager GDP growth:

The national income and product accounts updated last week by the BEA suggested that first quarter GDP growth was even weaker than previously indicated. GDP can be calculated in two ways, by summing up data on either what gets produced or the income generated by that production. Conceptually (and by definition) the two numbers should be exactly the same, but in practice you don't come up with quite the same number using different methods. Jeremy Nalewaik has argued that the income-based measure of GDP (referred to as gross domestic income, or GDI) may be a slightly better indicator of business cycle turning points. For example, GDI gave a clearer signal than GDP of a weakening economy in 2007. GDI had been showing a little stronger growth than the GDP indicator in early phase of the current recovery (2009:Q4-2010:Q2), but has been signaling weaker growth than GDP for the most recent quarters (2010:Q3-2011:Q1). The latest BEA numbers report that total U.S. real output was growing at a 1.8% annual rate in 2011:Q1 according to the GDP measure but at only a 1.2% rate according to GDI.
