Welcome to TeX.SE. The point of indenting a paragraph is to make it obvious that this is the start of a new paragraph. After a \section it is obvious that it is the start of a new paragraph so no indent is added. – Peter Grill Oct 30 '12 at 16:17
If you want indent first paragraph too: \usepackage{indentfirst}.
