Languages are handled by plugins that detect files of a particular language and then parse them and report the number of lines of whitespace, comments and code. If you're interested in getting a new ... [More] language added, check out: http://labs.ohloh.net/ohcount cheers stuart [Less]

I agree that detecting, counting and reporting on i18n file types would be excellent. Presumably they would be added just like new languages, and could even be done by motivated third parties (yes, I'm thinking of you here Ashar).

Better presentation of languages data. Idea for better presentation of the graphics at: http://www.ohloh.net/languages (1) Don't normalise across the entire site, to prevent the current occurrence ... [More] of many graphs which are apparently flat lines at zero. (2) Provide the Code / Commets / Blanks as a pie graph. (3) Add a little white space on the graph so that volatile graphs (i.e. c++ commits) don't get truncated by the graph boundary (4) Rather than (or as well as?) the drop-down to sort at the top of the page, decorate the labels with little icons to sort by that metric.

Project tag pages could relatively easily be seeded by labels and tags in repositories such as google code
