Is there a TikZ style attribute for adding default text to a node? For instance, I want to be able to do something like the following:
\begin{tikzpicture}[%
stuff/.style={%
draw,
text=Bla bla
},
]
\node at (0,0) [stuff] {};
\node at (0,1) [stuff] {};
\node at (0,2) [stuff] {};
\node at (0,3) [stuff] {};
\end{tikzpicture}
to produce a picture containing 4 nodes, each with the text "Bla bla". I want to be able to create nodes with the same text without having to add it manually.
I don't really get the question so I hope this is what you wanted. If you include a full document (such that we copy paste and see the problem on our systems) things are much more easier.
Here, you can change the default setting within a scope but your block style had a node distance which was resetting every time it is issued. I've made it 2mm such that we can see the difference easier.
\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,shapes.geometric,positioning}
\begin{document}
\begin{tikzpicture}[decision/.style={diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt},
block/.style ={rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, minimum height=2em},
cloud/.style ={draw, ellipse, minimum height=2em},
line/.style ={draw,-latex'},
node distance = 1cm,
auto]
\node [block] (1st) {1st};
\node [block, right= of 1st] (2nd1) {2nd1};
\begin{scope}[node distance=2mm and 10mm]%Here we change it for everything inside this scope
\node [block, above= of 2nd1] (2nd2) {2nd2};
\node [block, below= of 2nd1] (2nd3) {2nd3};
\node [block, right= of 2nd1] (3rd1) {3rd1};
\node [block, above= of 3rd1] (3rd2) {3rd2};
\node [block, above= of 3rd2] (3rd3) {3rd3};
\end{scope}
\node [block, below= of 3rd1] (3rd4) {3rd4};
\node [block, below= of 3rd4] (3rd5) {3rd5};
\path [line] (1st) -- (2nd1);
\path [line] (2nd1) -- (2nd2);
\path [line] (2nd1) -- (2nd3);
\path [line] (2nd2) -- (3rd3);
\path [line] (2nd1) -- (3rd1);
\path [line] (1st) -- (2nd1);
\end{tikzpicture}
\end{document}
Three suggestions:
You could add it relative to another node, for example
\node [above=of dec2] {Whatever text you wanted};
This requires \usetikzlibrary{positioning}.
You could place it relative to the current bounding box:
\node [above=of current bounding box.north] {Whatever text you wanted};
With this method you have to place the above line at the very end of the tikzpicture.
You could specify the position. I think (0,0) is the default position for a node without coordinates, so your start node is probably in (0,0). Hence, you could do
\node at (2,1) {Whatever text you wanted};
to place it two units to the right, and one unit above, the start node.

It's not exactly what it was designed for, but you can add fixed text to the
fontparameter:
