I wouldn't give too much on such style-guides. They are a good start, but in the end you or your team will develop own coding-styles.
EDIT: Rob Kam made a comment, that he want to find out more about these 'starting-conventions'.
That's a good point. But mostly you will join existing projects, open-source-projects or commercial, and the people working on it already have a code-convention. In a company probably exists already a code convention. If you start a new project, start with the conventions of another project you did before.
If you really start a new project with a new language you didn't used before ... then you might start with conventions of another language that is somehow similar (i.e. for a new oo-language you can use conventions from Java or Smalltalk) and adjust your conventions as you gain experience for the new language. As I started programming in Java I used my Pascal-coding-conventions. Some of the pascal-conventions didn't work very good for Java, but with the time I dropped some old conventions and developed new.
S.Lott had the idea to look into an open-source-project written in the language of your choice. That's a good idea to get some suggestions about good conventions. Srikanth had the good idea to ask for good conventions here at Stackoverflow. A very good idea, because with the time Stackoverflow will become a good reference for coding-conventions this way.
